Protein

Synaptotagmin-2

Gene
SYT2
Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

May have a regulatory role in the membrane interactions during trafficking of synaptic vesicles at the active zone of the synapse. It binds acidic phospholipids with a specificity that requires the presence of both an acidic head group and a diacyl backbone By similarity.

Cofactori

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