Function

[VTI1B_MOUSE] V-SNARE that mediates vesicle transport pathways through interactions with t-SNAREs on the target membrane. These interactions are proposed to mediate aspects of the specificity of vesicle trafficking and to promote fusion of the lipid bilayers. [STX7_MOUSE] May be involved in protein trafficking from the plasma membrane to the early endosome (EE) as well as in homotypic fusion of endocytic organelles. Mediates the endocytic trafficking from early endosomes to late endosomes and lysosomes (By similarity). [STX8_RAT] Vesicle trafficking protein that functions in the early secretory pathway, possibly by mediating retrograde transport from cis-Golgi membranes to the ER.

Publication Abstract from PubMed

SNARE proteins are crucial for intracellular membrane fusion in all eukaryotes. These proteins assemble into tight complexes that connect membranes and may induce fusion. The crystal structure of the neuronal core complex is represented by an unusually long bundle of four alpha-helices connected by 16 layers of mostly hydrophobic amino acids. Here we report the 1.9 A resolution crystal structure of an endosomal SNARE core complex containing four SNAREs: syntaxin 7, syntaxin 8, vti1b and endobrevin/VAMP-8. Despite limited sequence homology, the helix alignment and the layer structure of the endosomal complex are remarkably similar to those of the neuronal complex. However, subtle variations are evident that characterize different SNARE subfamilies. We conclude that the structure of the SNARE core complex is an evolutionarily conserved hallmark of all SNARE complexes and is intimately associated with the general role of SNAREs in membrane fusion.
