Comments
  • FUNCTION: May be involved in protein trafficking from the plasma membrane to the early endosome (EE) as well as in homotypic fusion of endocytic organelles. Mediates the endocytic trafficking from early endosomes to late endosomes and lysosomes (By similarity).
  • SUBUNIT: Interacts with STX8. Forms a SNARE complex with VTI1B, STX8 and VAMP8 which functions in the homotypic fusion of late endosomes. 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. Interacts with VPS11, VPS16 and VPS18. Found in a complex with VAMP8 and VTI1B in the liver. Part of the SNARE core complex containing VAMP8, STX8 and VTI1B (By similarity). Interacts with VPS33A.
  • SUBCELLULAR LOCATION: Early endosome membrane; Single-pass type IV membrane protein (By similarity).
  • TISSUE SPECIFICITY: Detected in all tissues tested. Highest expression is found in kidney followed by lung, spleen, heart and brain. Lower expression, in skeletal muscle, liver and testis.
  • SIMILARITY: Belongs to the syntaxin family.
  • SIMILARITY: Contains 1 t-SNARE coiled-coil homology domain.
