synaptotagmin-6; synaptotagmin VI; SytVI (SYT6)

Function

• may be involved in Ca+2-dependent exocytosis of secretory vesicles through Ca+2 & phospholipid binding to the C2 domain or may serve as Ca+2 sensors in the process of vesicular trafficking & exocytosis (putative)

Cofactor:

• binds 3 Ca+2 per subunit via the C2 domains (putative)

Structure

• homodimer
• can also form heterodimers with SytIII, SytV & SytX (putative)
• belongs to the synaptotagmin family
• contains 2 C2 domains

Compartment

• cytoplasmic vesicle, secretory vesicle
• synaptic vesicle membrane

Alternative splicing

named isoforms=2

More general terms

• synaptotagmin
