RA Colinge J., Superti-Furga G., Bennett K.L.; RL Submitted (OCT-2008) to UniProtKB. CC -!- FUNCTION: May modulate a step between vesicle priming, fusion and CC calcium-dependent neurotransmitter release by potentiating the CC interaction of synaptotagmins with the SNAREs and the plasma- CC membrane-associated protein SNAP25. Its phosphorylation state CC influences exocytotic protein interactions and may regulate CC synaptic vesicle exocytosis. May also have a role in the CC mechanisms of SNARE-mediated membrane fusion in non-neuronal cells CC (By similarity). CC -!- SUBUNIT: Associates with the SNARE complex. Interacts with SNAP23, CC SNAP25 and STX4A but not with STX1A, VAMP2 and SYT1. CC Phosphorylation increases its interaction with SNAP25 (By CC similarity). Interacts with RGS7. Component of the biogenesis of CC lysosome-related organelles (BLOC-1) complex which is required for CC normal biogenesis of specialized organelles of the endosomal- CC lysosomal system. Interacts with CEP110.

Membrane; CC Peripheral membrane protein; Cytoplasmic side (By similarity). CC Cytoplasmic vesicle membrane; Peripheral membrane protein; CC Cytoplasmic side (By similarity). Cytoplasmic vesicle, secretory CC vesicle, synaptic vesicle membrane; Peripheral membrane protein; CC Cytoplasmic side (Potential). Cell junction, synapse, synaptosome. CC Note=May be cytoplasmic and peripheral membrane bound or anchored CC to the vesicular membrane through an N-terminal signal anchor (By CC similarity). CC -!- PTM: Phosphorylated (By similarity).
