R-SNARE_STXBP5_6 cd15873
SNARE domain of STXBP5, STXBP6 and related proteins; Syntaxin binding protein 5 (STXBP5, also ...
1060-1117 1.01e-22

SNARE domain of STXBP5, STXBP6 and related proteins; Syntaxin binding protein 5 (STXBP5, also called Tomosyn), as well as its relative Syntaxin binding protein 6 (STXBP6, also called Amisyn) contains a C-terminal R-SNARE-like domain, which allows it to assemble into SNARE complexes, which in turn makes the complexes inactive and inhibits exocytosis. In general, SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins consist of coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain. The SNARE complex mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation. SNARE proteins are classified into four groups, Qa-, Qb-, Qc- and R-SNAREs, depending on whether the residue in the hydrophilic center layer of the four-helical bundle is a glutamine (Q) or arginine (R). Qc-, as well as Qa- and Qb-SNAREs, are localized to target organelle membranes, while R-SNARE is localized to vesicle membranes. They form unique complexes consisting of one member of each subgroup, that mediate fusion between a specific type of vesicles and their target organelle.

SNARE motif, subgroup R-SNARE; SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins consist of coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain. The SNARE complex mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation. SNARE proteins are classified into four groups, Qa-, Qb-, Qc- and R-SNAREs, depending on whether the residue in the hydrophilic center layer of the four-helical bundle is a glutamine (Q) or arginine (R). In contrast to Qa-, Qb- and Qc-SNAREs that are localized to target organelle membranes, R-SNAREs are localized to vesicle membranes. They form unique complexes consisting of one member of each subgroup, that mediate fusion between a specific type of vesicles and their target organelle. Their SNARE motifs form twisted and parallel heterotetrameric helix bundles. Examples for members of the Qa SNAREs are syntaxin 18, syntaxin 5, syntaxin 16, and syntaxin 1.

SNARE motif of VAMP4; The VAMP-4 (vesicle-associated membrane protein 4) protein belongs to the R-SNARE subgroup of SNAREs and interacts with syntaxin 16 (Qa), Vti1a (Qb) and syntaxin 6 (Qc). This complex plays a role in maintenance of Golgi ribbon structure and normal retrograde trafficking from the early endosome to the trans-Golgi network (TGN). SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins contain coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain. The SNARE complex mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation. SNARE proteins are classified into four groups, Qa-, Qb-, Qc- and R-SNAREs, depending on whether the residue in the hydrophilic center layer of the four-helical bundle is a glutamine (Q) or arginine (R). Qa-, as well as Qb- and Qc-SNAREs, are localized to target organelle membranes, while R-SNARE is localized to vesicle membranes. They form unique complexes consisting of one member of each subgroup, that mediate fusion between a specific type of vesicles and their target organelle. Their SNARE motifs form twisted and parallel heterotetrameric helix bundles.

SNARE motif of VAMP2; The VAMP-2 (vesicle-associated membrane protein 2, also called synaptobrevin-2) protein belongs to the R-SNARE subgroup of SNAREs and interacts with Syntaxin-1 (Qa) and SNAP-25(Qb/Qc), as well as syntaxin 12 (Qa) and SNAP23 (Qb/Qc). The complexes play a role in transport of secretory granule from trans-Golgi network to the plasma membrane, and in the transport from early endosomes to and from the plasma membrane, respectively. SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins contain coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain.

SNARE motif of VAMP8; The lysosomal VAMP8 (vesicle-associated membrane protein 8, also called endobrevin) protein belongs to the R-SNARE subgroup of SNAREs and interacts with STX17 (Qa) and SNAP29 (Qb/Qc). The complex plays a role in autophagosome-lysosome fusion via regulating the transport from early endosomes to multivesicular bodies. Autophagosome transports cytoplasmic materials including cytoplasmic proteins, glycogen, lipids, organelles, and invading bacteria to the lysosome for degradation. SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins contain coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain.

SNARE domain of STXBP5; Syntaxin binding protein 5 (STXBP5, also called Tomosyn), as well as its relative Syntaxin binding protein 6 (STXBP6, also called Amisyn) contains a C-terminal R-SNARE-like domain, which allows it to assemble into SNARE complexes, which in turn makes the complexes inactive and inhibits exocytosis. Tomosyn contains an N-terminal WD40 repeat region and has been shown to form complexes with SNAP-25 and syntaxin 1a, as well as SNAP-23 and syntaxin 4. In general, SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins consist of coiled-coil helices (called SNARE motifs) which mediate the interactions between SNARE proteins, and a transmembrane domain. The SNARE complex mediates membrane fusion, important for trafficking of newly synthesized proteins, recycling of pre-existing proteins and organelle formation.
