Protein

Synaptotagmin-3

Gene

SYT3

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at transcript 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.By similarity

Cofactori

Binds 3 calcium ions per subunit. The ions are bound to the C2 domains (By similarity).By similarity
