 429-563 1.77e-91

Deltex C-terminal domain; This is the C-terminal domains found in members of the Deltex family of proteins which comprises five members (DTX1, 2, 3, 4, and 3L). This conserved C-terminal region of about 150 residues of the Deltex family, is preceded by a RING E3 ligase domain in four of the members. Crystal structure of the Deltex C-terminal (DTC) domain reveals a fold composed of a central beta-sheet lined with two long parallel alpha-helices.

 360-431 2.24e-45

RING finger, H2 subclass, found in E3 ubiquitin-protein ligase Deltex2 (DTX2) and similar proteins; DTX2, also known as RING finger protein 58, together with DTX1 and DTX4, forms a family of related proteins that are the mammalian homologs of Drosophila Deltex, a known regulator of Notch signals. Like DTX1 and DTX4, DTX2 is expressed in thymocytes. It interacts with the intracellular domain of Notch receptors and acts as a negative regulator of Notch signals in T cells. However, the endogenous levels of DTX1 and DTX2 is not important for regulating Notch signals during thymocyte development. DTX2 contains two Notch-binding WWE domains at the N-terminus that physically interact with the Notch ankyrin domains, a proline-rich motif that shares homology with SH3-binding domains, and a C3H2C3-type RING-H2 finger at the C-terminus. It also harbors two nuclear localization signals.

 360-431 2.24e-45

RING finger, H2 subclass, found in E3 ubiquitin-protein ligase Deltex2 (DTX2) and similar proteins; DTX2, also known as RING finger protein 58, together with DTX1 and DTX4, forms a family of related proteins that are the mammalian homologs of Drosophila Deltex, a known regulator of Notch signals. Like DTX1 and DTX4, DTX2 is expressed in thymocytes. It interacts with the intracellular domain of Notch receptors and acts as a negative regulator of Notch signals in T cells. However, the endogenous levels of DTX1 and DTX2 is not important for regulating Notch signals during thymocyte development. DTX2 contains two Notch-binding WWE domains at the N-terminus that physically interact with the Notch ankyrin domains, a proline-rich motif that shares homology with SH3-binding domains, and a C3H2C3-type RING-H2 finger at the C-terminus. It also harbors two nuclear localization signals.

 358-426 5.27e-33

RING finger, H2 subclass, found in E3 ubiquitin-protein ligase deltex1 (DTX1), deltex4 (DTX4), and similar proteins; DTX1 functions as a Notch downstream transcription regulator that mediates a Notch signal to block differentiation of neural progenitor cells. It interacts with the transcription coactivator p300 and inhibits transcription activation mediated by the neural specific transcription factor MASH1. It is also a transcription target of nuclear factor of activated T cells (NFAT) and participates in T cell anergy and Foxp3 protein level maintenance in vivo. Moreover, DTX1 appears to promote B-cell development at the expense of T-cell development. It also promotes protein kinase C theta degradation and sustains Casitas B-lineage lymphoma expression. DTX4, also known as RING finger protein 155, shares the highest degree of sequence similarity with DTX1 and likely interacts with the intracellular domain of Notch as well. Both DTX1 and DTX4 contain two Notch-binding WWE domains at the N-terminus that physically interact with the Notch ankyrin domains, a proline-rich motif that shares homology with SH3-binding domains, and a C3H2C3-type RING-H2 finger at the C-terminus. They also harbor two nuclear localization signals.

RING finger, H2 subclass, found in E3 ubiquitin-protein ligase Deltex1 (DTX1), Deltex2 (DTX2), Deltex4 (DTX4), and similar proteins; This subfamily contains the vertebrate homologs of Drosophila melanogaster Deltex, specifically DTX1, DTX2, and DTX4, and other similar proteins mainly from eumetazoa. The vertebrate homologs of Deltex are involved in Notch signaling and neurogenesis. Mammalian DTX1 is most closely related to the Drosophila Deltex. Both of them bind to SH3-domain containing protein Grb2 and further inhibit E2A. DTX1 functions as a Notch downstream transcription regulator. It interacts with the transcription coactivator p300 and inhibits transcription activation mediated by the neural specific transcription factor MASH1. It is also a transcription target of nuclear factor of activated T cells (NFAT) and participates in T cell anergy and Foxp3 protein level maintenance in vivo. Moreover, DTX1 promotes protein kinase C theta degradation and sustains Casitas B-lineage lymphoma expression. DTX4, also known as RING finger protein 155, shares the highest degree of sequence similarity with DTX1. So it likely interacts with the intracellular domain of Notch as well. Like DTX1 and DTX4, DTX2 is expressed in thymocytes. It interacts with the intracellular domain of Notch receptors and acts as a negative regulator of Notch signals in T cells. However, the endogenous levels of DTX1 and DTX2 is not important for regulating Notch signals during thymocyte development. In contrast to other DTXs, DTX3 does not contain two Notch-binding WWE domains at the N-terminus, but rather a short unique N-terminal domain. It does not interact with the intracellular domain of Notch. In addition, it has a different class of RING finger (C3HC4 type or RING-HC subclass), compared with the other DTXs which harbor a C3H2C3-type RING-H2 finger. Thus DTX3 is not included in this subfamily. Drosophila melanogaster Deltex also does not belong to this subfamily.

 361-422 1.34e-05

H2 subclass of RING (RING-H2) fingers and its variants; The RING finger is a specialized type of Zn-finger of 40 to 60 residues that binds two atoms of zinc. It is defined by the "cross-brace" motif that chelates zinc atoms by eight amino acid residues, typically Cys or His, arranged in a characteristic spacing. Canonical RING motifs have been categorized into two major subclasses, RING-HC (C3HC4-type) and RING-H2 (C3H2C3-type), according to their Cys/His content. There are also many variants of RING fingers: some have different Cys/His patterns while some lack a single Cys or His residue at typical Zn ligand positions (the fourth or eighth zinc ligand is prevalently exchanged for an Asp, which can indeed chelate Zn in a RING finger as well). This family corresponds to the H2 subclass of RING (RING-H2) finger proteins that are characterized by containing C3H2C3-type canonical RING-H2 fingers or noncanonical RING-H2 finger variants, including C4HC3- (RING-CH alias RINGv), C3H3C2-, C3H2C2D-, C3DHC3-, and C4HC2H-type modified RING-H2 fingers. The canonical RING-H2 finger has been defined as C-X2-C-X(9-39)-C-X(1-3)-H-X(2-3)-H-X2-C-X(4-48)-C-X2-C, X is any amino acid and the number of X residues varies in different fingers. It binds two Zn ions in a unique "cross-brace" arrangement, which distinguishes it from tandem zinc fingers and other similar motifs. RING-H2 finger can be found in a group of diverse proteins with a variety of cellular functions, including oncogenesis, development, viral replication, signal transduction, the cell cycle and apoptosis. Many of them are ubiquitin-protein ligases (E3s) that serves as a scaffold for binding to ubiquitin-conjugating enzymes (E2s, also referred to as ubiquitin carrier proteins or UBCs) in close proximity to substrate proteins, which enables efficient transfer of ubiquitin from E2 to the substrates.

RNF32 contains two C3H2C3-type RING-H2 fingers separated by an IQ domain of unknown function. Although the biological function of RNF32 remains unclear, proteins with double RING-H2 fingers may act as scaffolds for binding several proteins that function in the same pathway. This model corresponds to the second RING-H2 finger.

RING finger, HC subclass, found in protein Deltex-3-like (DTX3L) and similar proteins; DTX3L, also known as B-lymphoma- and BAL-associated protein (BBAP) or Rhysin-2 (Rhysin2), is a RING-domain E3 ubiquitin-protein ligase that regulates endosomal sorting of the G protein-coupled receptor CXCR4 from endosomes to lysosomes. It also regulates subcellular localization of its partner protein, B aggressive lymphoma (BAL), by a dynamic nucleocytoplasmic trafficking mechanism. DTX3L has a unique N-terminus, but lacks the highly basic N-terminal motif and the central proline-rich motif present in other Deltex (DTX) family members, such as DTX1, DTX2, and DTX4. Moreover, its C-terminal region is highly homologous to DTX3. It includes a C3HC4-type RING-HC finger, and a previously unidentified C-terminal domain. DTX3L can associate with DTX1 through its unique N-terminus and further enhance self-ubiquitination.

 360-422 6.86e-03

RING finger, H2 subclass, found in Saccharomyces cerevisiae transmembrane E3 ubiquitin-protein ligase 1 (TUL1) and similar proteins; This subfamily includes Saccharomyces cerevisiae TUL1, Schizosaccharomyces pombe DSC E3 ubiquitin ligase complex subunit 1 (DSC1), and Arabidopsis thaliana protein FLYING SAUCER 2 (FLY2). TUL1 is the catalytic component of DSC E3 ubiquitin ligase complexes that tag proteins present in Golgi, endosome and vacuole membranes and function in protein homeostasis under non-stress conditions, and support a role in protein quality control. It mediates ubiquitination of vacuolar proteins such as CPS1, PPN1, PEP12 and other proteins containing exposed hydrophilic residues within their transmembrane domains, leading to their sorting into internal vesicles in late endosomes. TUL1 also targets the unpalmitoylated endosomal SNARE TLG1 to the multivesicular body (MVB) pathway. DSC1, also known as defective for SREBP cleavage protein 1, is the catalytic component of the DSC E3 ubiquitin ligase complex required for the sre1 transcriptional activator proteolytic cleavage to release the soluble transcription factor from the membrane in low oxygen or sterol conditions. FLY2 acts as an E3 ubiquitin-protein ligase that may be involved in xylem development. Members of this subfamily contain a C3H2C3-type RING-H2 finger.
