Protein

Synaptic vesicle glycoprotein 2A

Gene

Sv2a

Organism
Rattus norvegicus (Rat)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

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.
Receptor for the botulinium neurotoxin type A/BOTA.

Miscellaneous

Identified as the brain binding-site for the antiepileptic drug levetiracetam/lev.
