SV2B and epilepsy: Another synapse-associated protein, synaptic vesicle glycoprotein 2B (SV2B), is localized to synaptic vesicles and functions in the regulation of vesicle trafficking, exocytosis, and calcium homeostasis in the presynaptic terminal, leading to the control of synaptic functionality [36,37], and it has been implicated in human epilepsy [37].
