Vesicle associated membrane proteins (VAMP) are a family of SNARE proteins
SNARE (protein)
SNARE proteins are a large protein superfamily consisting of more than 60 members in yeast and mammalian cells....

 with similar structure, and are mostly involved in vesicle fusion
Vesicle fusion
Vesicle fusion is the merging of a vesicle with other vesicles or a part of a cell membrane. In the latter case, it is the end stage of secretion from secretory vesicles, where their contents are expelled from the cell through exocytosis at the porosome...

    • 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
    Endocytosis
    Endocytosis is a process by which cells absorb molecules by engulfing them. It is used by all cells of the body because most substances important to them are large polar molecules that cannot pass through the hydrophobic plasma or cell membrane...
