Vesicle transport through interaction with t-SNAREs homolog 1A (Vti1a)

V-SNARE that mediates vesicle transport pathways through interactions with t-SNAREs on the target membrane. These interactions are suggested to mediate aspects of the specificity of vesicle trafficking and to promote fusion of the lipid bilayers.

Involved in vesicular transport from the late endosomes to the trans-Golgi network. Together with VAMP7, involved in an non- conventional RAB1-dependent traffic route to the cell surface used by KCNIP1 and KCND2.
