Arf-like 6 (Arl6) GTPase; Arl6 (Arf-like 6) forms a subfamily of the Arf family of small GTPases. Arl6 expression is limited to the brain and kidney in adult mice, but it is expressed in the neural plate and somites during embryogenesis, suggesting a possible role for Arl6 in early development. Arl6 is also believed to have a role in cilia or flagella function. Several proteins have been identified that bind Arl6, including Arl6 interacting protein (Arl6ip), and SEC61beta, a subunit of the heterotrimeric conducting channel SEC61p. Based on Arl6 binding to these effectors, Arl6 is also proposed to play a role in protein transport, membrane trafficking, or cell signaling during hematopoietic maturation. At least three specific homozygous Arl6 mutations in humans have been found to cause Bardet-Biedl syndrome, a disorder characterized by obesity, retinopathy, polydactyly, renal and cardiac malformations, learning disabilities, and hypogenitalism. Older literature suggests that Arl6 is a part of the Arl4/Arl7 subfamily, but analyses based on more recent sequence data place Arl6 in its own subfamily.

small GTP-binding protein domain; Proteins with a small GTP-binding domain recognized by this model include Ras, RhoA, Rab11, translation elongation factor G, translation initiation factor IF-2, tetratcycline resistance protein TetM, CDC42, Era, ADP-ribosylation factors, tdhF, and many others. In some proteins the domain occurs more than once.This model recognizes a large number of small GTP-binding proteins and related domains in larger proteins. Note that the alpha chains of heterotrimeric G proteins are larger proteins in which the NKXD motif is separated from the GxxxxGK[ST] motif (P-loop) by a long insert and are not easily detected by this model.

 19-178 1.72e-76

ADP-ribosylation factor(Arf)/Arf-like (Arl) small GTPases; Arf (ADP-ribosylation factor)/Arl (Arf-like) small GTPases. Arf proteins are activators of phospholipase D isoforms. Unlike Ras proteins they lack cysteine residues at their C-termini and therefore are unlikely to be prenylated. Arfs are N-terminally myristoylated. Members of the Arf family are regulators of vesicle formation in intracellular traffic that interact reversibly with membranes of the secretory and endocytic compartments in a GTP-dependent manner. They depart from other small GTP-binding proteins by a unique structural device, interswitch toggle, that implements front-back communication from N-terminus to the nucleotide binding site. Arf-like (Arl) proteins are close relatives of the Arf, but only Arl1 has been shown to function in membrane traffic like the Arf proteins. Arl2 has an unrelated function in the folding of native tubulin, and Arl4 may function in the nucleus. Most other Arf family proteins are so far relatively poorly characterized. Thus, despite their significant sequence homologies, Arf family proteins may regulate unrelated functions.

Arf-like 3 (Arl3) GTPase; Arl3 (Arf-like 3) is an Arf family protein that differs from most Arf family members in the N-terminal extension. In is inactive, GDP-bound form, the N-terminal extension forms an elongated loop that is hydrophobically anchored into the membrane surface; however, it has been proposed that this region might form a helix in the GTP-bound form. The delta subunit of the rod-specific cyclic GMP phosphodiesterase type 6 (PDEdelta) is an Arl3 effector. Arl3 binds microtubules in a regulated manner to alter specific aspects of cytokinesis via interactions with retinitis pigmentosa 2 (RP2). It has been proposed that RP2 functions in concert with Arl3 to link the cell membrane and the cytoskeleton in photoreceptors as part of the cell signaling or vesicular transport machinery. In mice, the absence of Arl3 is associated with abnormal epithelial cell proliferation and cyst formation.

ARF-like small GTPases; ARF, ADP-ribosylation factor; Ras homologues involved in vesicular transport. Activator of phospholipase D isoforms. Unlike Ras proteins they lack cysteine residues at their C-termini and therefore are unlikely to be prenylated. ARFs are N-terminally myristoylated. Contains ATP/GTP-binding motif (P-loop).

Arf-like 5 (Arl5) and 8 (Arl8) GTPases; Arl5/Arl8 subfamily. Arl5 (Arf-like 5) and Arl8, like Arl4 and Arl7, are localized to the nucleus and nucleolus. Arl5 is developmentally regulated during embryogenesis in mice. Human Arl5 interacts with the heterochromatin protein 1-alpha (HP1alpha), a nonhistone chromosomal protein that is associated with heterochromatin and telomeres, and prevents telomere fusion. Arl5 may also play a role in embryonic nuclear dynamics and/or signaling cascades. Arl8 was identified from a fetal cartilage cDNA library. It is found in brain, heart, lung, cartilage, and kidney. No function has been assigned for Arl8 to date.

 20-177 5.10e-51

ADP ribosylation factor 1 (Arf1); Arl1 subfamily. Arl1 (Arf-like 1) localizes to the Golgi complex, where it is believed to recruit effector proteins to the trans-Golgi network. Like most members of the Arf family, Arl1 is myristoylated at its N-terminal helix and mutation of the myristoylation site disrupts Golgi targeting. In humans, the Golgi-localized proteins golgin-97 and golgin-245 have been identified as Arl1 effectors. Golgins are large coiled-coil proteins found in the Golgi, and these golgins contain a C-terminal GRIP domain, which is the site of Arl1 binding. Additional Arl1 effectors include the GARP (Golgi-associated retrograde protein)/VFT (Vps53) vesicle-tethering complex and Arfaptin 2. Arl1 is not required for exocytosis, but appears necessary for trafficking from the endosomes to the Golgi. In Drosophila zygotes, mutation of Arl1 is lethal, and in the host-bloodstream form of Trypanosoma brucei, Arl1 is essential for viability.

 14-177 2.09e-49

ADP ribosylation factor 6 (Arf6); Arf6 subfamily. Arf6 (ADP ribosylation factor 6) proteins localize to the plasma membrane, where they perform a wide variety of functions. In its active, GTP-bound form, Arf6 is involved in cell spreading, Rac-induced formation of plasma membrane ruffles, cell migration, wound healing, and Fc-mediated phagocytosis. Arf6 appears to change the actin structure at the plasma membrane by activating Rac, a Rho family protein involved in membrane ruffling. Arf6 is required for and enhances Rac formation of ruffles. Arf6 can regulate dendritic branching in hippocampal neurons, and in yeast it localizes to the growing bud, where it plays a role in polarized growth and bud site selection. In leukocytes, Arf6 is required for chemokine-stimulated migration across endothelial cells. Arf6 also plays a role in down-regulation of beta2-adrenergic receptors and luteinizing hormone receptors by facilitating the release of sequestered arrestin to allow endocytosis. Arf6 is believed to function at multiple sites on the plasma membrane through interaction with a specific set of GEFs, GAPs, and effectors. Arf6 has been implicated in breast cancer and melanoma cell invasion, and in actin remodelling at the invasion site of Chlamydia infection.

 18-177 3.63e-49

ADP-ribosylation factor-1 (Arf1) and ADP-ribosylation factor-5 (Arf5); The Arf1-Arf5-like subfamily contains Arf1, Arf2, Arf3, Arf4, Arf5, and related proteins. Arfs1-5 are soluble proteins that are crucial for assembling coat proteins during vesicle formation. Each contains an N-terminal myristoylated amphipathic helix that is folded into the protein in the GDP-bound state. GDP/GTP exchange exposes the helix, which anchors to the membrane. Following GTP hydrolysis, the helix dissociates from the membrane and folds back into the protein. A general feature of Arf1-5 signaling may be the cooperation of two Arfs at the same site. Arfs1-5 are generally considered to be interchangeable in function and location, but some specific functions have been assigned. Arf1 localizes to the early/cis-Golgi, where it is activated by GBF1 and recruits the coat protein COPI. It also localizes to the trans-Golgi network (TGN), where it is activated by BIG1/BIG2 and recruits the AP1, AP3, AP4, and GGA proteins. Humans, but not rodents and other lower eukaryotes, lack Arf2. Human Arf3 shares 96% sequence identity with Arf1 and is believed to generally function interchangeably with Arf1. Human Arf4 in the activated (GTP-bound) state has been shown to interact with the cytoplasmic domain of epidermal growth factor receptor (EGFR) and mediate the EGF-dependent activation of phospholipase D2 (PLD2), leading to activation of the activator protein 1 (AP-1) transcription factor. Arf4 has also been shown to recognize the C-terminal sorting signal of rhodopsin and regulate its incorporation into specialized post-Golgi rhodopsin transport carriers (RTCs). There is some evidence that Arf5 functions at the early-Golgi and the trans-Golgi to affect Golgi-associated alpha-adaptin homology Arf-binding proteins (GGAs).

Arf-like 2 (Arl2) GTPase; Arl2 (Arf-like 2) GTPases are members of the Arf family that bind GDP and GTP with very low affinity. Unlike most Arf family proteins, Arl2 is not myristoylated at its N-terminal helix. The protein PDE-delta, first identified in photoreceptor rod cells, binds specifically to Arl2 and is structurally very similar to RhoGDI. Despite the high structural similarity between Arl2 and Rho proteins and between PDE-delta and RhoGDI, the interactions between the GTPases and their effectors are very different. In its GTP bound form, Arl2 interacts with the protein Binder of Arl2 (BART), and the complex is believed to play a role in mitochondrial adenine nucleotide transport. In its GDP bound form, Arl2 interacts with tubulin- folding Cofactor D; this interaction is believed to play a role in regulation of microtubule dynamics that impact the cytoskeleton, cell division, and cytokinesis.

Arf-like 4 (Arl4) and 7 (Arl7) GTPases; Arl4 (Arf-like 4) is highly expressed in testicular germ cells, and is found in the nucleus and nucleolus. In mice, Arl4 is developmentally expressed during embryogenesis, and a role in somite formation and central nervous system differentiation has been proposed. Arl7 has been identified as the only Arf/Arl protein to be induced by agonists of liver X-receptor and retinoid X-receptor and by cholesterol loading in human macrophages. Arl7 is proposed to play a role in transport between a perinuclear compartment and the plasma membrane, apparently linked to the ABCA1-mediated cholesterol secretion pathway. Older literature suggests that Arl6 is a part of the Arl4/Arl7 subfamily, but analyses based on more recent sequence data place Arl6 in its own subfamily.

Arf-like tumor suppressor gene 1 (ARLTS1 or Arl11); ARLTS1 (Arf-like tumor suppressor gene 1), also known as Arl11, is a member of the Arf family of small GTPases that is believed to play a major role in apoptotic signaling. ARLTS1 is widely expressed and functions as a tumor suppressor gene in several human cancers. ARLTS1 is a low-penetrance suppressor that accounts for a small percentage of familial melanoma or familial chronic lymphocytic leukemia (CLL). ARLTS1 inactivation seems to occur most frequently through biallelic down-regulation by hypermethylation of the promoter. In breast cancer, ARLTS1 alterations were typically a combination of a hypomorphic polymorphism plus loss of heterozygosity. In a case of thyroid adenoma, ARLTS1 alterations were polymorphism plus promoter hypermethylation. The nonsense polymorphism Trp149Stop occurs with significantly greater frequency in familial cancer cases than in sporadic cancer cases, and the Cys148Arg polymorphism is associated with an increase in high-risk familial breast cancer.

Sar1 is an essential component of COPII vesicle coats; Sar1 is an essential component of COPII vesicle coats involved in export of cargo from the ER. The GTPase activity of Sar1 functions as a molecular switch to control protein-protein and protein-lipid interactions that direct vesicle budding from the ER. Activation of the GDP to the GTP-bound form of Sar1 involves the membrane-associated guanine nucleotide exchange factor (GEF) Sec12. Sar1 is unlike all Ras superfamily GTPases that use either myristoyl or prenyl groups to direct membrane association and function, in that Sar1 lacks such modification. Instead, Sar1 contains a unique nine-amino-acid N-terminal extension. This extension contains an evolutionarily conserved cluster of bulky hydrophobic amino acids, referred to as the Sar1-N-terminal activation recruitment (STAR) motif. The STAR motif mediates the recruitment of Sar1 to ER membranes and facilitates its interaction with mammalian Sec12 GEF leading to activation.

 20-177 9.15e-35

(ADP-ribosylation factor domain protein 1 (ARD1); ARD1 (ADP-ribosylation factor domain protein 1) is an unusual member of the Arf family. In addition to the C-terminal Arf domain, ARD1 has an additional 46-kDa N-terminal domain that contains a RING finger domain, two predicted B-Boxes, and a coiled-coil protein interaction motif. This domain belongs to the TRIM (tripartite motif) or RBCC (RING, B-Box, coiled-coil) family. Like most Arfs, the ARD1 Arf domain lacks detectable GTPase activity. However, unlike most Arfs, the full-length ARD1 protein has significant GTPase activity due to the GAP (GTPase-activating protein) activity exhibited by the 46-kDa N-terminal domain. The GAP domain of ARD1 is specific for its own Arf domain and does not bind other Arfs. The rate of GDP dissociation from the ARD1 Arf domain is slowed by the adjacent 15 amino acids, which act as a GDI (GDP-dissociation inhibitor) domain. ARD1 is ubiquitously expressed in cells and localizes to the Golgi and to the lysosomal membrane. Two Tyr-based motifs in the Arf domain are responsible for Golgi localization, while the GAP domain controls lysosomal localization.

 20-177 1.17e-33

Arf-related protein 1 (Arfrp1); Arfrp1 (Arf-related protein 1), formerly known as ARP, is a membrane-associated Arf family member that lacks the N-terminal myristoylation motif. Arfrp1 is mainly associated with the trans-Golgi compartment and the trans-Golgi network, where it regulates the targeting of Arl1 and the GRIP domain-containing proteins, golgin-97 and golgin-245, onto Golgi membranes. It is also involved in the anterograde transport of the vesicular stomatitis virus G protein from the Golgi to the plasma membrane, and in the retrograde transport of TGN38 and Shiga toxin from endosomes to the trans-Golgi network. Arfrp1 also inhibits Arf/Sec7-dependent activation of phospholipase D. Deletion of Arfrp1 in mice causes embryonic lethality at the gastrulation stage and apoptosis of mesodermal cells, indicating its importance in development.

Arl2-like protein 1 (Arl2l1) and Arl13; Arl2l1 (Arl2-like protein 1) and Arl13 form a subfamily of the Arf family of small GTPases. Arl2l1 was identified in human cells during a search for the gene(s) responsible for Bardet-Biedl syndrome (BBS). Like Arl6, the identified BBS gene, Arl2l1 is proposed to have cilia-specific functions. Arl13 is found on the X chromosome, but its expression has not been confirmed; it may be a pseudogene.

 23-177 5.70e-18

Rat sarcoma (Ras)-like superfamily of small guanosine triphosphatases (GTPases); Ras-like GTPase superfamily. The Ras-like superfamily of small GTPases consists of several families with an extremely high degree of structural and functional similarity. The Ras superfamily is divided into at least four families in eukaryotes: the Ras, Rho, Rab, and Sar1/Arf families. This superfamily also includes proteins like the GTP translation factors, Era-like GTPases, and G-alpha chain of the heterotrimeric G proteins. Members of the Ras superfamily regulate a wide variety of cellular functions: the Ras family regulates gene expression, the Rho family regulates cytoskeletal reorganization and gene expression, the Rab and Sar1/Arf families regulate vesicle trafficking, and the Ran family regulates nucleocytoplasmic transport and microtubule organization. The GTP translation factor family regulates initiation, elongation, termination, and release in translation, and the Era-like GTPase family regulates cell division, sporulation, and DNA replication. Members of the Ras superfamily are identified by the GTP binding site, which is made up of five characteristic sequence motifs, and the switch I and switch II regions.

 19-147 5.93e-16

Signal recognition particle receptor, beta subunit (SR-beta), together with SR-alpha, forms the heterodimeric signal recognition particle (SRP); Signal recognition particle receptor, beta subunit (SR-beta). SR-beta and SR-alpha form the heterodimeric signal recognition particle (SRP or SR) receptor that binds SRP to regulate protein translocation across the ER membrane. Nascent polypeptide chains are synthesized with an N-terminal hydrophobic signal sequence that binds SRP54, a component of the SRP. SRP directs targeting of the ribosome-nascent chain complex (RNC) to the ER membrane via interaction with the SR, which is localized to the ER membrane. The RNC is then transferred to the protein-conducting channel, or translocon, which facilitates polypeptide translation across the ER membrane or integration into the ER membrane. SR-beta is found only in eukaryotes; it is believed to control the release of the signal sequence from SRP54 upon binding of the ribosome to the translocon. High expression of SR-beta has been observed in human colon cancer, suggesting it may play a role in the development of this type of cancer.

 45-134 6.50e-09

Alpha subunit of G proteins (guanine nucleotide binding); The alpha subunit of G proteins contains the guanine nucleotide binding site. The heterotrimeric GNP-binding proteins are signal transducers that communicate signals from many hormones, neurotransmitters, chemokines, and autocrine and paracrine factors. Extracellular signals are received by receptors, which activate the G proteins, which in turn route the signals to several distinct intracellular signaling pathways. The alpha subunit of G proteins is a weak GTPase. In the resting state, heterotrimeric G proteins are associated at the cytosolic face of the plasma membrane and the alpha subunit binds to GDP. Upon activation by a receptor GDP is replaced with GTP, and the G-alpha/GTP complex dissociates from the beta and gamma subunits. This results in activation of downstream signaling pathways, such as cAMP synthesis by adenylyl cyclase, which is terminated when GTP is hydrolized and the heterotrimers reconstitute.

 29-136 2.82e-08

Ras-related in brain (Rab) family of small guanosine triphosphatases (GTPases); Rab GTPases form the largest family within the Ras superfamily. There are at least 60 Rab genes in the human genome, and a number of Rab GTPases are conserved from yeast to humans. Rab GTPases are small, monomeric proteins that function as molecular switches to regulate vesicle trafficking pathways. The different Rab GTPases are localized to the cytosolic face of specific intracellular membranes, where they regulate distinct steps in membrane traffic pathways. In the GTP-bound form, Rab GTPases recruit specific sets of effector proteins onto membranes. Through their effectors, Rab GTPases regulate vesicle formation, actin- and tubulin-dependent vesicle movement, and membrane fusion. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which mask C-terminal lipid binding and promote cytosolic localization. While most unicellular organisms possess 5-20 Rab members, several have been found to possess 60 or more Rabs; for many of these Rab isoforms, homologous proteins are not found in other organisms. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins. Since crystal structures often lack C-terminal residues, the lipid modification site is not available for annotation in many of the CDs in the hierarchy, but is included where possible.

Rab GTPase family 18 (Rab18); Rab18 subfamily. Mammalian Rab18 is implicated in endocytic transport and is expressed most highly in polarized epithelial cells. However, trypanosomal Rab, TbRAB18, is upregulated in the BSF (Blood Stream Form) stage and localized predominantly to elements of the Golgi complex. In human and mouse cells, Rab18 has been identified in lipid droplets, organelles that store neutral lipids. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation.

Rab GTPase families 18 (Rab18) and 32 (Rab32); Rab38/Rab32 subfamily. Rab32 and Rab38 are members of the Rab family of small GTPases. Human Rab32 was first identified in platelets but it is expressed in a variety of cell types, where it functions as an A-kinase anchoring protein (AKAP). Rab38 has been shown to be melanocyte-specific. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP.

 28-137 7.30e-06

Ras-related nuclear proteins (Ran)/TC4 family of small GTPases; Ran GTPase is involved in diverse biological functions, such as nuclear transport, spindle formation during mitosis, DNA replication, and cell division. Among the Ras superfamily, Ran is a unique small G protein. It does not have a lipid modification motif at the C-terminus to bind to the membrane, which is often observed within the Ras superfamily. Ran may therefore interact with a wide range of proteins in various intracellular locations. Like other GTPases, Ran exists in GTP- and GDP-bound conformations that interact differently with effectors. Conversion between these forms and the assembly or disassembly of effector complexes requires the interaction of regulator proteins. The intrinsic GTPase activity of Ran is very low, but it is greatly stimulated by a GTPase-activating protein (RanGAP1) located in the cytoplasm. By contrast, RCC1, a guanine nucleotide exchange factor that generates RanGTP, is bound to chromatin and confined to the nucleus. Ran itself is mobile and is actively imported into the nucleus by a mechanism involving NTF-2. Together with the compartmentalization of its regulators, this is thought to produce a relatively high concentration of RanGTP in the nucleus.

 23-172 1.14e-05

E. coli Ras-like protein (Era)-like GTPase; The Era (E. coli Ras-like protein)-like family includes several distinct subfamilies (TrmE/ThdF, FeoB, YihA (EngB), Era, and EngA/YfgK) that generally show sequence conservation in the region between the Walker A and B motifs (G1 and G3 box motifs), to the exclusion of other GTPases. TrmE is ubiquitous in bacteria and is a widespread mitochondrial protein in eukaryotes, but is absent from archaea. The yeast member of TrmE family, MSS1, is involved in mitochondrial translation; bacterial members are often present in translation-related operons. FeoB represents an unusual adaptation of GTPases for high-affinity iron (II) transport. YihA (EngB) family of GTPases is typified by the E. coli YihA, which is an essential protein involved in cell division control. Era is characterized by a distinct derivative of the KH domain (the pseudo-KH domain) which is located C-terminal to the GTPase domain. EngA and its orthologs are composed of two GTPase domains and, since the sequences of the two domains are more similar to each other than to other GTPases, it is likely that an ancient gene duplication, rather than a fusion of evolutionarily distinct GTPases, gave rise to this family.

 29-117 2.58e-05

Rab GTPase families 34 (Rab34) and 36 (Rab36); Rab34/Rab36 subfamily. Rab34, found primarily in the Golgi, interacts with its effector, Rab-interacting lysosomal protein (RILP). This enables its participation in microtubular dynenin-dynactin-mediated repositioning of lysosomes from the cell periphery to the Golgi. A Rab34 (Rah) isoform that lacks the consensus GTP-binding region has been identified in mice. This isoform is associated with membrane ruffles and promotes macropinosome formation. Rab36 has been mapped to human chromosome 22q11.2, a region that is homozygously deleted in malignant rhabdoid tumors (MRTs). However, experimental assessments do not implicate Rab36 as a tumor suppressor that would enable tumor formation through a loss-of-function mechanism. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins.

Rab GTPase family 9 (Rab9); Rab9 is found in late endosomes, together with mannose 6-phosphate receptors (MPRs) and the tail-interacting protein of 47 kD (TIP47). Rab9 is a key mediator of vesicular transport from late endosomes to the trans-Golgi network (TGN) by redirecting the MPRs. Rab9 has been identified as a key component for the replication of several viruses, including HIV1, Ebola, Marburg, and measles, making it a potential target for inhibiting a variety of viruses. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation.

 20-99 1.71e-03

Rab GTPase family 15 (Rab15); Rab15 colocalizes with the transferrin receptor in early endosome compartments, but not with late endosomal markers. It codistributes with Rab4 and Rab5 on early/sorting endosomes, and with Rab11 on pericentriolar recycling endosomes. It is believed to function as an inhibitory GTPase that regulates distinct steps in early endocytic trafficking. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization.

Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state.

 24-175 2.50e-03

Obg-like family of GTPases consist of five subfamilies: Obg, DRG, YyaF/YchF, Ygr210, and NOG1; The Obg-like subfamily consists of five well-delimited, ancient subfamilies, namely Obg, DRG, YyaF/YchF, Ygr210, and NOG1. Four of these groups (Obg, DRG, YyaF/YchF, and Ygr210) are characterized by a distinct glycine-rich motif immediately following the Walker B motif (G3 box). Obg/CgtA is an essential gene that is involved in the initiation of sporulation and DNA replication in the bacteria Caulobacter and Bacillus, but its exact molecular role is unknown. Furthermore, several OBG family members possess a C-terminal RNA-binding domain, the TGS domain, which is also present in threonyl-tRNA synthetase and in bacterial guanosine polyphosphatase SpoT. Nog1 is a nucleolar protein that might function in ribosome assembly. The DRG and Nog1 subfamilies are ubiquitous in archaea and eukaryotes, the Ygr210 subfamily is present in archaea and fungi, and the Obg and YyaF/YchF subfamilies are ubiquitous in bacteria and eukaryotes. The Obg/Nog1 and DRG subfamilies appear to form one major branch of the Obg family and the Ygr210 and YchF subfamilies form another branch. No GEFs, GAPs, or GDIs for Obg have been identified.

 67-138 3.75e-03

Rab GTPase family 33 includes Rab33A and Rab33B; Rab33B/Rab33A subfamily. Rab33B is ubiquitously expressed in mouse tissues and cells, where it is localized to the medial Golgi cisternae. It colocalizes with alpha-mannose II. Together with the other cisternal Rabs, Rab6A and Rab6A', it is believed to regulate the Golgi response to stress and is likely a molecular target in stress-activated signaling pathways. Rab33A (previously known as S10) is expressed primarily in the brain and immune system cells. In humans, it is located on the X chromosome at Xq26 and its expression is down-regulated in tuberculosis patients. Experimental evidence suggests that Rab33A is a novel CD8+ T cell factor that likely plays a role in tuberculosis disease processes. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization. Most Rab GTPases contain a lipid modification site at the C-terminus, with sequence motifs CC, CXC, or CCX. Lipid binding is essential for membrane attachment, a key feature of most Rab proteins.

Rat sarcoma (Ras) family of small guanosine triphosphatases (GTPases); The Ras family of the Ras superfamily includes classical N-Ras, H-Ras, and K-Ras, as well as R-Ras, Rap, Ral, Rheb, Rhes, ARHI, RERG, Rin/Rit, RSR1, RRP22, Ras2, Ras-dva, and RGK proteins. Ras proteins regulate cell growth, proliferation and differentiation. Ras is activated by guanine nucleotide exchange factors (GEFs) that release GDP and allow GTP binding. Many RasGEFs have been identified. These are sequestered in the cytosol until activation by growth factors triggers recruitment to the plasma membrane or Golgi, where the GEF colocalizes with Ras. Active GTP-bound Ras interacts with several effector proteins: among the best characterized are the Raf kinases, phosphatidylinositol 3-kinase (PI3K), RalGEFs and NORE/MST1. Most Ras proteins contain a lipid modification site at the C-terminus, with a typical sequence motif CaaX, where a = an aliphatic amino acid and X = any amino acid. Lipid binding is essential for membrane attachment, a key feature of most Ras proteins. Due to the presence of truncated sequences in this CD, the lipid modification site is not available for annotation.

 18-142 6.76e-03

Rab GTPase-like family 2 (Rab-like2); RabL2 (Rab-like2) subfamily. RabL2s are novel Rab proteins identified recently which display features that are distinct from other Rabs, and have been termed Rab-like. RabL2 contains RabL2a and RabL2b, two very similar Rab proteins that share > 98% sequence identity in humans. RabL2b maps to the subtelomeric region of chromosome 22q13.3 and RabL2a maps to 2q13, a region that suggests it is also a subtelomeric gene. Both genes are believed to be expressed ubiquitously, suggesting that RabL2s are the first example of duplicated genes in human proximal subtelomeric regions that are both expressed actively. Like other Rab-like proteins, RabL2s lack a prenylation site at the C-terminus. The specific functions of RabL2a and RabL2b remain unknown. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization.

 18-99 8.74e-03

Rab GTPase family J-like (RabJ-like); RJLs are found in many protists and as chimeras with C-terminal DNAJ domains in deuterostome metazoa. They are not found in plants, fungi, and protostome metazoa, suggesting a horizontal gene transfer between protists and deuterostome metazoa. RJLs lack any known membrane targeting signal and contain a degenerate phosphate/magnesium-binding 3 (PM3) motif, suggesting an impaired ability to hydrolyze GTP. GTPase activating proteins (GAPs) interact with GTP-bound Rab and accelerate the hydrolysis of GTP to GDP. Guanine nucleotide exchange factors (GEFs) interact with GDP-bound Rabs to promote the formation of the GTP-bound state. Rabs are further regulated by guanine nucleotide dissociation inhibitors (GDIs), which facilitate Rab recycling by masking C-terminal lipid binding and promoting cytosolic localization.
