|UniProt annotation for VAMP7_HUMAN » Vesicle-associated membrane protein 7|
|FUNCTION: Involved in the targeting and/or fusion of transport vesicles to their target membrane during transport of proteins from the early endosome to the lysosome. Required for heterotypic fusion of late endosomes with lysosomes and homotypic lysosomal fusion. Required for calcium regulated lysosomal exocytosis. Involved in the export of chylomicrons from the endoplasmic reticulum to the cis Golgi. Required for exocytosis of mediators during eosinophil and neutrophil degranulation, and target cell killing by natural killer cells. Required for focal exocytosis of late endocytic vesicles during phagosome formation. SUBUNIT: Component of the SNARE complex composed of STX4, SNAP23 and VAMP7 that binds SYT7 during lysosomal exocytosis. Component of the SNARE complex composed of STX7, STX8, VAMP7 and VTI1B that is required for heterotypic fusion of late endosomes with lysosomes. May interact with STX17 (By similarity). TISSUE SPECIFICITY: Detected in all tissues tested. MISCELLANEOUS: The gene coding for this protein is located in the pseudoautosomal region 2 (PAR2) of X and Y chromosomes. MISCELLANEOUS: Loss-of-function mutant (antisense inhibition) displays impaired granzyme B release and target cell killing by natural killer cells.|
