Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

May be involved in Ca2+-dependent exocytosis of secretory vesicles through Ca2+ and phospholipid binding to the C2 domain or may serve as Ca2+ sensors in the process of vesicular trafficking and exocytosis. May mediate Ca2+-regulation of exocytosis in acrosomal reaction in sperm (By similarity).By similarity

Cofactori

Ca2+By similarityNote: Binds 3 Ca2+ ions per subunit. The ions are bound to the C2 domains.By similarity
