Protein Structure

UniProt Annotation

Function

Plays a role in vesicle maturation during exocytosis as a target of the diacylglycerol second messenger pathway. Is involved in neurotransmitter release by acting in synaptic vesicle priming prior to vesicle fusion and participates in the activity- depending refilling of readily releasable vesicle pool (RRP) (By similarity). Essential for synaptic vesicle maturation in a subset of excitatory/glutamatergic but not inhibitory/GABA-mediated synapses. {ECO:0000250, ECO:0000269PubMed:12070347}.

Subcellular Localization

Cytoplasm. Membrane; Peripheral membrane protein. Golgi apparatus. Cell junction, synapse {ECO:0000250}. Note=Localized to synapses (By similarity). Translocates to the Golgi in response to phorbol ester binding. {ECO:0000250}.
