[[http://www.uniprot.org/uniprot/VTI1B_MOUSE 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. [[http://www.uniprot.org/uniprot/STX7_MOUSE 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). [[http://www.uniprot.org/uniprot/STX8_RAT STX8_RAT]] Vesicle trafficking protein that functions in the early secretory pathway, possibly by mediating retrograde transport from cis-Golgi membranes to the ER.
[https://www.uniprot.org/uniprot/VAMP8_RAT VAMP8_RAT] SNAREs, soluble N-ethylmaleimide-sensitive factor-attachment protein receptors, are essential proteins for fusion of cellular membranes. SNAREs localized on opposing membranes assemble to form a trans-SNARE complex, an extended, parallel four alpha-helical bundle that drives membrane fusion. VAMP8 is a SNARE involved in autophagy through the direct control of autophagosome membrane fusion with the lysososome membrane via its interaction with the STX17-SNAP29 binary t-SNARE complex (By similarity). Also required for dense-granule secretion in platelets (By similarity). Also plays a role in regulated enzyme secretion in pancreatic acinar cells (By similarity). Involved in the abscission of the midbody during cell division, which leads to completely separate daughter cells (PubMed:12737809). Involved in the homotypic fusion of early and late endosomes (PubMed:10982406, PubMed:11029036). Participates also in the activation of type I interferon antiviral response through a TRIM6-dependent mechanism (By similarity).[UniProtKB:Q9BV40]<ref>PMID:10982406</ref> <ref>PMID:11029036</ref> <ref>PMID:12737809</ref>
