Description
Product Characteristics: 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 in liver cells. SUBCELLULAR LOCATION: Cytoplasmic vesicle, secretory vesicle membrane, Single-pass type IV membrane protein. Golgi apparatus, trans-Golgi network membrane, Single-pass type IV membrane protein. Late endosome membrane, Single-pass type IV membrane protein. Lysosome membrane, Single-pass type IV membrane protein. Endoplasmic reticulum membrane, Single-pass type IV membrane protein.

TISSUE SPECIFICITY: Detected in all tissues tested.,Vesicle Transport,Vesicle-associated membrane protein 7, SYBL1, Synaptobrevin-like protein 1, Tetanus-insensitive VAMP, Ti-VAMP, SYBL1
Target Information: This gene encodes a transmembrane protein that is a member of the soluble N-ethylmaleimide-sensitive factor attachment protein receptor (SNARE) family. The encoded protein localizes to late endosomes and lysosomes and is involved in the fusion of transport vesicles to their target membranes. Alternate splicing results in multiple transcript variants.[provided by RefSeq, Jun 2010]
