SYT3 (human), recombinant protein

Protein function: Ca(2+) sensor involved in Ca(2+)-dependent exocytosis of secretory vesicles through Ca(2+) and phospholipid binding to the C2 domain. Ca(2+) induces binding of the C2-domains to phospholipid membranes and to assembled SNARE-complexes, both actions contribute to triggering exocytosis. Plays a role in dendrite formation by melanocytes (PubMed:23999003). [The UniProt Consortium]
