UniProtKB - Q29397 (SV2A_BOVIN)
Protein
Synaptic vesicle glycoprotein 2A
Gene
SV2A
Organism
Bos taurus (Bovine)
Status
Functioni
Plays a role in the control of regulated secretion in neural and endocrine cells, enhancing selectively low-frequency neurotransmission. Positively regulates vesicle fusion by maintaining the readily releasable pool of secretory vesicles (By similarity).
