UniProt annotation for VTI1_YEAST » t-SNARE VTI1
FUNCTION: t-SNARE found in various SNARE complexes involved in multiple transport pathways. The composition of the t-SNARE complexes is specific for a limited number of v-SNAREs and therefore allows only the vesicles carrying the matching v-SNARE to fuse.

SUBUNIT: Forms SNARE complexes with the t-SNAREs VAM3 and VAM7, and the v-SNAREs NYV1 and YKT6 on vacuolar membranes, which are involved in biosynthetic transport pathways to the vacuole and in homotypic vacuole fusion. Forms SNARE complexes with the cis-Golgi t-SNARE SED5 and the v-SNAREs SFT1 and YTK6, which are involved in retrograde traffic to the cis-Golgi compartment. Forms SNARE complexes with the t-SNAREs TLG1 and TLG2, and either the v-SNARE SNC1 or SNC2, which are involved in traffic from early endosomes to the trans-Golgi network (TGN). Forms SNARE complexes with the t-SNAREs PEP12 and either SYN8 or TLG1, and the v-SNARE SNC1, which are involved in traffic from the TGN to the prevacuolar compartment (PVC).
