Atypical FERM-like domain C-lobe of Sorting nexin 17; SNX17 is a beta1-integrin-tail-binding protein that interacts with the free kindlin-binding site in endosomes to stabilize beta1 integrins, resulting in their recycling to the cell surface where they can be reused. SNX17 contains a N-terminal PX domain, a FERM-like domain, and a unique C-terminal region. SNX17 binds Ras GTPase through its FERM-like domains. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. These interactions place the PX-FERM-like proteins at a hub of endosomal sorting and signaling processes. These proteins participate in a network of interactions that will impact on both endosomal protein trafficking and compartment specific Ras signaling cascades. The typical FERM domain has a cloverleaf tripart structure composed of: (1) FERM_N (A-lobe or F1); (2) FERM_M (B-lobe, or F2); and (3) FERM_C (C-lobe or F3). The C-lobe/F3 within the FERM domain is part of the PH domain family. FERM domains are found in cytoskeletal-associated proteins such as ezrin, moesin, radixin, 4.1R, and merlin. These proteins provide a link between the membrane and cytoskeleton and are involved in signal transduction pathways. The FERM domain is also found in protein tyrosine phosphatases (PTPs), the tyrosine kinases FAK and JAK, in addition to other proteins involved in signaling. This domain is structurally similar to the PH and PTB domains and consequently is capable of binding to both peptides and phospholipids at different sites. : Pssm-ID: 270145 Cd Length: 113 Bit Score: 169.06 E-value: 4.10e-51

SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX17 is known to regulate the trafficking and processing of a number of proteins. It binds some members of the low-density lipoprotein receptor (LDLR) family such as LDLR, VLDLR, ApoER2, and others, regulating their endocytosis. It also binds P-selectin and may regulate its lysosomal degradation. SNX17 is highly expressed in neurons. It binds amyloid precursor protein (APP) and may be involved in its intracellular trafficking and processing to amyloid beta peptide, which plays a central role in the pathogenesis of Alzheimer's disease. The biological function of SNX31 is unknown. : Pssm-ID: 132795 Cd Length: 104 Bit Score: 162.88 E-value: 8.02e-49

The Phox Homology domain, a phosphoinositide binding module; The PX domain is a phosphoinositide (PI) binding module involved in targeting proteins to membranes. Proteins containing PX domains interact with PIs and have been implicated in highly diverse functions such as cell signaling, vesicular trafficking, protein sorting, lipid modification, cell polarity and division, activation of T and B cells, and cell survival. Many members of this superfamily bind phosphatidylinositol-3-phosphate (PI3P) but in some cases, other PIs such as PI4P or PI(3,4)P2, among others, are the preferred substrates. In addition to protein-lipid interaction, the PX domain may also be involved in protein-protein interaction, as in the cases of p40phox, p47phox, and some sorting nexins (SNXs). The PX domain is conserved from yeast to humans and is found in more than 100 proteins. The majority of PX domain-containing proteins are SNXs, which play important roles in endosomal sorting.

This subfamily is composed of YPT35 proteins from the fungal subkingdom Dikarya. The PX domain is involved in targeting of proteins to PI-enriched membranes, and may also be involved in protein-protein interaction. The PX domain of YPT35 binds to phosphatidylinositol 3-phosphate (PI3P). It also serves as a protein interaction domain, binding to members of the Yip1p protein family, which localize to the ER and Golgi. YPT35 is mainly associated with endosomes and together with Yip1p proteins, may be involved in a specific function in the endocytic pathway.

The phosphoinositide binding Phox Homology Domain of Cytokine-Independent Survival Kinase; The PX domain is a phosphoinositide (PI) binding module present in many proteins with diverse functions. Cytokine-independent survival kinase (CISK), also called Serum- and Glucocorticoid-induced Kinase 3 (SGK3), plays a role in cell growth and survival. It is expressed in most tissues and is most abundant in the embryo and adult heart and spleen. It was originally discovered in a screen for antiapoptotic genes. It phosphorylates and inhibits the proapoptotic proteins, Bad and FKHRL1. CISK/SGK3 also regulates many transporters, ion channels, and receptors. It plays a critical role in hair follicle morphogenesis and hair cycling. N-terminal to a catalytic kinase domain, CISK contains a PX domain which binds highly phosphorylated PIs, directs membrane localization, and regulates the enzyme's activity.

The phosphoinositide binding Phox Homology domain of yeast MDM1p; The PX domain is a phosphoinositide binding (PI) module present in many proteins with diverse functions such as cell signaling, vesicular trafficking, protein sorting, and lipid modification, among others. Yeast MDM1p is a filament-like protein localized in punctate structures distributed throughout the cytoplasm. It plays an important role in nuclear and mitochondrial transmission to daughter buds. Members of this subfamily show similar domain architectures as some sorting nexins (SNXs). Some members are similar to SNX19 in that they contain an N-terminal PXA domain, a central PX domain, and a C-terminal domain that is conserved in some SNXs. Others are similar to SNX13 and SNX14, which also harbor these three domains as well as a regulator of G protein signaling (RGS) domain in between the PXA and PX domains. SNXs make up the largest group among PX domain containing proteins. They are involved in regulating membrane traffic and protein sorting in the endosomal system. The PX domain of SNXs binds PIs and targets the protein to PI-enriched membranes. SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway.

SNXs differ from each other in PI-binding specificity and affinity, and the presence of other protein-protein interaction domains, which help determine subcellular localization and specific function in the endocytic pathway. SNX13, also called RGS-PX1, contains an N-terminal PXA domain, a regulator of G protein signaling (RGS) domain, a PX domain, and a C-terminal domain that is conserved in some SNXs. It specifically binds to the stimulatory subunit of the heterotrimeric G protein G(alpha)s, serving as its GTPase activating protein, through the RGS domain. It preferentially binds phosphatidylinositol-3-phosphate (PI3P) through the PX domain and is localized in early endosomes. SNX13 is involved in endosomal sorting of EGFR into multivesicular bodies (MVB) for delivery to the lysosome. Pssm-ID: 132783 Cd Length: 120 Bit Score: 38.02 E-value: 2.42e-03
