81-143 | 7.72e-03 | |||
Inter-Src homology 2 (iSH2) helical domain of Class IA Phosphoinositide 3-kinase Regulatory subunit 2, PIK3R2, also called p85beta; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. They play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation, and apoptosis. They are classified according to their substrate specificity, regulation, and domain structure. Class IA PI3Ks are heterodimers of a p110 catalytic (C) subunit and a p85-related regulatory (R) subunit. The R subunit down-regulates PI3K basal activity, stabilizes the C subunit, and plays a role in the activation downstream of tyrosine kinases. All R subunits contain two SH2 domains that flank an intervening helical domain (iSH2), which binds to the N-terminal adaptor-binding domain (ABD) of the catalytic subunit. p85beta, also called PIK3R2, contains N-terminal SH3 and GAP domains. It is expressed ubiquitously but at lower levels than p85alpha. Its expression is increased in breast and colon cancer, correlates with tumor progression, and enhanced invasion. During viral infection, the viral nonstructural (NS1) protein binds p85beta specifically, which leads to PI3K activation and the promotion of viral replication. Mice deficient with PIK3R2 develop normally and exhibit moderate metabolic and immunological defects. Pssm-ID: 214019 [Multi-domain] Cd Length: 161 Bit Score: 36.21 E-value: 7.72e-03

SAM domain of MLTK subfamily; SAM (sterile alpha motif) domain of MLTK subfamily is a protein-protein interaction domain. Besides SAM domain, these proteins have N-terminal protein tyrosine kinase domain and leucine-zipper motif. Proteins of this group act as mitogen-activated protein triple kinase in a number of MAPK cascades. They can be activated by autophosphorylation in response to stress signals. MLTK-alpha is known to phosphorylate histone H3. In mammals, MLTKs participate in the activation of the JNK/SAPK, p38, ERK5 pathways, the transcriptional factor NF-kB, in the regulation of the cell cycle checkpoint, and in the induction of apoptosis in a hepatoma cell line. Some members of this subfamily are proto-oncogenes, thus MLTK-alpha is involved in neoplasmic cell transformation and/or skin cancer development in athymic nude mice. Based on in vivo coprecipitation experiments in mammalian cells, it has been demonstrated that MLTK proteins might form homodimers/oligomers via their SAM domains.

SAM domain of Ste50_like (ubc2) subfamily; SAM (sterile alpha motif) domain of Ste50-like (or Ubc2 for Ustilago bypass of cyclase) subfamily is a putative protein-protein interaction domain. This group includes only fungal proteins. Basidiomycetes have an N-terminal SAM domain, central UBQ domain, and C-terminal SH3 domain, while Ascomycetes lack the SH3 domain. Ubc2 of Ustilago maydis is a major virulence and maize pathogenicity factor. It is required for filamentous growth (the budding haploid form of Ustilago maydis is a saprophyte, while filamentous dikaryotic form is a pathogen). Also the Ubc2 protein is involved in the pheromone-responsive morphogenesis via the MAP kinase cascade. The SAM domain is necessary for ubc2 function; deletion of SAM eliminates this function.

Proteins of this subfamily are multidomain diacylglycerol kinases with a SAM domain located at the C-terminus. DGK-delta proteins participate in signal transduction. They regulate the level of second messengers such as diacylglycerol and phosphatidic acid. In particular DGK-delta is involved in the regulation of clathrin-dependent endocytosis. The SAM domain of DGK-delta proteins can form high molecular weight homooligomers through head-to-tail interactions as well as heterooligomers with the SAM domain of DGK-eta proteins. The oligomerization plays a role in the regulation of the DGK-delta intracellular localization: it inhibits the translocation of the protein to the plasma membrane from the cytoplasm.

SAM domain of EPH family of tyrosine kinase receptors; SAM (sterile alpha motif) domain of EPH (erythropoietin-producing hepatocyte) family of receptor tyrosine kinases is a C-terminal signal transduction module located in the cytoplasmic region of these receptors. SAM appears to mediate cell-cell initiated signal transduction via binding proteins to a conserved tyrosine that is phosphorylated. In some cases the SAM domain mediates homodimerization/oligomerization and plays a role in the clustering process necessary for signaling. EPH kinases are the largest family of receptor tyrosine kinases. They are classified into two groups based on their abilities to bind ephrin-A and ephrin-B ligands. The EPH receptors are involved in regulation of cell movement, shape, and attachment during embryonic development; they control cell-cell interactions in the vascular, nervous, epithelial, and immune systems, and in many tumors. They are potential molecular markers for cancer diagnostics and potential targets for cancer therapy. Pssm-ID: 188887 Cd Length: 61 Bit Score: 35.28 E-value: 2.65e-03

SAM domain of aveugle-like subfamily; SAM (sterile alpha motif) domain of SAM_aveugle-like subfamily is a protein-protein interaction domain. In Drosophila, the aveugle (AVE) protein (also known as HYP (Hyphen)) is involved in normal photoreceptor differentiation, and required for epidermal growth factor receptor (EGFR) signaling between ras and raf genes during eye development and wing vein formation. SAM domain of the HYP(AVE) protein interacts with SAM domain of CNK, the multidomain scaffold protein connector enhancer of kinase suppressor of ras. CNK/HYP(AVE) complex interacts with KSR (kinase suppressor of Ras) protein. This interaction leads to stimulation of Ras-dependent Raf activation. This subfamily also includes vertebrate AVE homologs - Samd10 and Samd12 proteins. Their exact function is unknown, but they may play a role in signal transduction during embryogenesis.

iSH2_PIK3R2 | cd12926 | Inter-Src homology 2 (iSH2) helical domain of Class IA Phosphoinositide 3-kinase Regulatory ... |
81-143 | 7.72e-03 | |||
Inter-Src homology 2 (iSH2) helical domain of Class IA Phosphoinositide 3-kinase Regulatory subunit 2, PIK3R2, also called p85beta; PI3Ks catalyze the transfer of the gamma-phosphoryl group from ATP to the 3-hydroxyl of the inositol ring of D-myo-phosphatidylinositol (PtdIns) or its derivatives. They play an important role in a variety of fundamental cellular processes, including cell motility, the Ras pathway, vesicle trafficking and secretion, immune cell activation, and apoptosis. They are classified according to their substrate specificity, regulation, and domain structure. Class IA PI3Ks are heterodimers of a p110 catalytic (C) subunit and a p85-related regulatory (R) subunit. The R subunit down-regulates PI3K basal activity, stabilizes the C subunit, and plays a role in the activation downstream of tyrosine kinases. All R subunits contain two SH2 domains that flank an intervening helical domain (iSH2), which binds to the N-terminal adaptor-binding domain (ABD) of the catalytic subunit. p85beta, also called PIK3R2, contains N-terminal SH3 and GAP domains. It is expressed ubiquitously but at lower levels than p85alpha. Its expression is increased in breast and colon cancer, correlates with tumor progression, and enhanced invasion. During viral infection, the viral nonstructural (NS1) protein binds p85beta specifically, which leads to PI3K activation and the promotion of viral replication. Mice deficient with PIK3R2 develop normally and exhibit moderate metabolic and immunological defects. Pssm-ID: 214019 [Multi-domain] Cd Length: 161 Bit Score: 36.21 E-value: 7.72e-03
