 50-116 1.30e-38

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 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.

 51-106 2.14e-10

SNARE motif of YKT6; Ykt6 forms complexes with syntaxin-5 (Qa), GS28 (Qb) and either Bet1 (Qc) or GS15 (Qc). This complex regulates the early secretory pathway of eukaryotic cells at the level of the transport from the ER-Golgi intermediate compartment (ERGIC) to the cis-Golgi and transport from the trans-Golgi network to the cis-Golgi, respectively. Ykt6 is a member of the R-SNARE subfamily of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins which contain coiled-coil helices (called SNARE motifs) that 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 motif of SEC22; SEC22 forms complexes with syntaxin 18 (Qa), Sec20 (Qb) and USE1 (Qc), and with syntaxin 5 (Qa), GS27 (Qb) and Bet1 (Qc). These complexes are involved in the transport from cis-Golgi to the endoplasmic reticulum (ER) and in the transport from endoplasmic reticulum (ER) to the ER-Golgi intermediate compartment (ERGIC), respectively. SEC22 is a member of the R-SNARE subfamily of SNARE (soluble N-ethylmaleimide-sensitive factor attachment protein receptor) proteins which contain coiled-coil helices (called SNARE motifs) that 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.
