Vesicle-associated membrane protein

Jump to: navigation, search

Vesicle associated membrane protein (VAMP) family of proteins includes proteins with similar structure.

  • VAMP3 (known as cellubrevin) is ubiquitously expressed and participates in regulated and constitutive exocytosis as a constituent of secretory granules and secretory vesicles.
  • VAMP5 and VAMP7 (SYBL1) participate in constitutive exocytosis.
    • VAMP5 is a constituent of secretory vesicles, myotubes and tubulovesicular structures.
    • VAMP7 is found both in secretory granules and endosomes.
  • VAMP8 (known as endobrevin) participates in endocytosis and is found in early endosomes. VAMP8 also participates the regulated exocytosis in pancreatic acinar cells.
  • VAMP4 is involved in transport from the Golgi.[1]
