Synaptic vesicle glycoprotein 2A (SV2A) is a transmembrane protein belonging to a family of keratan sulfate proteoglycans, located on the synaptic vesicles of mammalian neuronal and endocrine cells. It's encoded by the SV2A gene.

SV2A is the most widely expressed isoform of the SV2 family (which also includes the SV2B and SV2C proteins) found in all brain regions. The role of the SV2 proteins is not well understood, however they are thought to be involved in regulating vesicular processes.

The SV2A protein is a target of the anti-epileptic drugs (anticonvulsants) levetiracetam and brivaracetam but it is not clear how these drug affect SV2A activity.
