PrecautionsVTI1b Antibody is for research use only and not for use in diagnostic or therapeutic procedures.
Protein Information
Name VTI1B
Synonyms VTI1, VTI1L, VTI1L1, VTI2
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. May be concerned with increased secretion of cytokines associated with cellular senescence.
Cellular Location Late endosome membrane; Single-pass type IV membrane protein. Lysosome membrane. Cytoplasmic granule
Tissue Location Expressed in all tissues examined.

Vesicle transport through interaction with t-SNAREs homolog 1 (VTI1a and VTI1b) are involved in vesicular transport from the late endosomes to the trans-Golgi network (1). They are both localized in the trans-Golgi network, with VTI1a also found in the Golgi apparatus and VTI1b in endosomes (2,3). It is thought that VTI1b along with the SNARE protein VAMP8 mediates the fusion of antimicrobial and canonical autophagosomes with lysosomes, an essential process for autophagy (4).
