296-358 7.24e-41

SAM domain of Smaug subfamily; SAM (sterile alpha motif) domain of Smaug proteins is an RNA recognition domain. It binds a specific RNA motif known as Smaug recognition element (SRE). Among members of this group are invertebrate Smaug (Smg) proteins and vertebrate Smaug1 and Smaug2 proteins. They are involved in post-transcriptional control during early embryogenesis in animals. In Drosophila, Smaug protein is a translational repressor of mRNA of Nanos (Nos) protein. Gradient of Nanos is required for proper abdominal segmentation. SAM domain interacts specifically with the Nanos mRNA regulatory regions. Moreover, Smaug protein is involved in regulation of specific maternal transcripts degradation in Drosophila early embryo via recruitment of the CCR4/POP2/NOT deadenylase.

SAM domain (Sterile alpha motif); It has been suggested that SAM is an evolutionarily conserved protein binding domain that is involved in the regulation of numerous developmental processes in diverse eukaryotes. The SAM domain can potentially function as a protein interaction module through its ability to homo- and heterooligomerise with other SAM domains.

SAM (Sterile alpha motif ); SAM (sterile alpha motif) domain of Smaug-like subfamily proteins is an RNA binding domain. SAM interacts with stem-loop structures in target mRNAs. Proteins of this subfamily are post-transcriptional regulators involved in mRNA silencing and deadenylation; they can be implicated in transcript stability regulation and vacuolar protein transport as well. SAM_Smaug-like domain-containing proteins are found in metazoa from yeast to human. In animals they are active during early embryogenesis.

301-362 5.65e-13

SAM domain of VTS1 RNA-binding proteins; SAM (sterile alpha motif) domain of VTS1 subfamily proteins is RNA binding domain located in the C-terminal region. SAM interacts with stem-loop structures of mRNA. Proteins of this subfamily participate in regulation of transcript stability and degradation, and also may be involved in vacuolar protein transport regulation. VTS1 protein of S.cerevisiae induces mRNA degradation via the major deadenylation-dependent mRNA decay pathway; VTS1 recruits CCR4/POP2/NOT deadenylase complex to target mRNA. The recruitment is the initial step resulting in poly(A) tail removal transcripts. Potentially SAM domain may be responsible not only for RNA binding but also for deadenylase binding.

302-359 2.66e-08

SAM domain of BICC1 (bicaudal) subfamily; SAM (sterile alpha motif) domain of BICC1 (bicaudal) subfamily is a protein-protein interaction domain. Proteins of this group have N-terminal K homology RNA-binding vigilin-like repeats and a C-terminal SAM domain. BICC1 is involved in the regulation of embryonic differentiation. It plays a role in the regulation of Dvl (Dishevelled) signaling, particularly in the correct cilia orientation and nodal flow generation. In Drosophila, disruption of BICC1 can disturb the normal migration direction of the anterior follicle cell of oocytes; the specific function of SAM is to recruit whole protein to the periphery of P-bodies. In mammals, mutations in this gene are associated with polycystic kidney disease and it was suggested that the BICC1 protein can indirectly interact with ANKS6 protein (ANKS6 is also associated with polycystic kidney disease) through some protein and RNA intermediates.

SAM (Sterile alpha motif ); SAM (Sterile Alpha Motif) domain is a module consisting of approximately 70 amino acids. This domain is found in the Fungi/Metazoa group and in a restricted number of bacteria. Proteins with SAM domains are represented by a wide variety of domain architectures and have different intracellular localization, including nucleus, cytoplasm and membranes. SAM domains have diverse functions. They can interact with proteins, RNAs and membrane lipids, contain site of phosphorylation and/or kinase docking site, and play a role in protein homo and hetero dimerization/oligomerization in processes ranging from signal transduction to regulation of transcription. Mutations in SAM domains have been linked to several diseases.

297-366 5.62e-04

SAM domain of AIDA1AB-like proteins, repeat 2; SAM (sterile alpha motif) domain repeat 2 of AIDA1AB-like proteins is a protein-protein interaction domain. AIDA1AB-like proteins have two tandem SAM domains. They may form an intramolecular head-to-tail homodimer. One of two basic motifs of the nuclear localization signal (NLS) is located within helix 5 of the SAM2 (motif HKRK). This signal plays a role in decoupling of SAM2 from SAM1, thus facilitating translocation of this type proteins into the nucleus. SAM domains of the AIDA1AB-like subfamily can directly bind ubiquitin and participate in regulating the degradation of ubiquitinated EphA receptors, particularly EPH-A8 receptor. Additionally AIDA1AB-like proteins may participate in the regulation of nucleoplasmic coilin protein interactions.

SAM domain of Ste11_fungal subfamily; SAM (sterile alpha motif) domain of Ste11 subfamily is a protein-protein interaction domain. Proteins of this subfamily have SAM domain at the N-terminus and protein kinase domain at the C-terminus. They participate in regulation of mating pheromone response, invasive growth and high osmolarity growth response. MAP triple kinase Ste11 from S.cerevisia is known to interact with Ste20 kinase and Ste50 regulator. These kinases are able to form homodimers interacting through their SAM domains as well as heterodimers or heterogenous complexes when either SAM domain of monomeric or homodimeric form of Ste11 interacts with Ste50 regulator.
