General annotation (Comments)

Function	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. Involved in vesicular transport from the late endosomes to the trans-Golgi network. Along with VAMP7, involved in an non-conventional RAB1-dependent traffic route to the cell surface used by KCNIP1 and KCND2. May be involved in increased cytokine secretion associated with cellular senescence. Ref.5 Ref.6 UniProtKB O89116
Subunit structure	Interacts with distinct SNARE complexes that contain either STX5 or STX6 By similarity. Interacts with NAPA and, to a lesser extent, with NAPG By similarity. Also identified in a complex containing STX13 and VAMP4 By similarity.
Subcellular location	Cytoplasmic vesicle. Golgi apparatus membrane; Single-pass type IV membrane protein By similarity Ref.6.
Sequence similarities	Belongs to the VTI1 family. UniProtKB O89116
