Background
Vesicle transport through interaction with t-SNAREs homolog 1 (Vti1) has two protein members, Vti1a and Vti1b. Human Vti1 was first identified as a homolog of the yeast v-SNARE Vti1p and was able to functionally rescue the phenotype of Vti1p-deficient yeast (1). The mammalian proteins Vti1a and Vti1b exhibit distinct but overlapping localization. Vti1a and Vti1b are both localized in the trans-Golgi network, with Vti1a also found in the Golgi apparatus and Vti1b in endosomes (2). Vti1 proteins have been implicated in a number of protein-protein interactions with partners such as VAMP4, syntaxin 6, syntaxin 8, syntaxin 16, and synaptobrevin (2-4). Research studies demonstrate that Vti1a residing on synaptic vesicles is involved in maintaining spontaneous neurotransmitter release (5).
