SV2A is a Galactose Transporter

By Marisa Sanchez, Molecular and Cellular Biology ’15

SV2A is a synaptic vesicle protein, which participates in the regulation of neurotransmitter release in humans. SV2A is expressed in neurons and endocrine cells. The exact function of SV2A is still unknown, but it has been identified that SV2A is the binding site for the antiepileptic drug, levetiracetam. Levetiracetam reduces presynaptic glutamate release, especially in neurons with high frequency firing. Abnormally enhanced glutamatergic neurotransmission with high frequency neural firing is found in epilepsy and several neurodegenerative disorders, such as Parkinson’s disease, Alzheimer’s disease, and Huntington’s disease.
