InterPro : IPR022308

Name  Synaptic vesicle protein SV2 Short Name  SV2
Type  Family Description  SV2 proteins are abundant synaptic vesicle proteins expressed in two major (SV2A and SV2B) and one minor isoform (SV2C) that resemble transporter proteins. SV2B knockout mice are phenotypically normal while SV2A- and SV2A/SV2Bdouble knockout mice exhibit severe seizures and die postnatally. Without SV2 proteins, presynaptic Ca2+accumulation during consecutive action potentials causes abnormal increases in neurotransmitter release that destabilise synaptic circuits and induce epilepsy [].
