Synaptotagmin-5 (SYT5)

May be involved in Ca(2+)-dependent exocytosis of secretory vesicles through Ca(2+) and phospholipid binding to the C2 domain or may serve as Ca(2+) sensors in the process of vesicular trafficking and exocytosis. Regulates the Ca(2+)- dependent secretion of norepinephrine in PC12 cells.

Needed for export in the endocytic recycling compartment to the cell surface (By similarity). .
