physiological function | serine racemase is a key player in neuron activity and in neuropathologies. D-serine is the essential co-agonist of the N-methyl-D-aspartate receptor, that mediates neurotransmission, synaptic plasticity, cell migration and long term potentiation. High and low D-serine levels have been associated with distinct neuropathologies, aging-related deficits and psychiatric disorders due to either hyper- or hypo-activation of the receptor. Serine racemase dual activity is regulated by ATP, divalent cations, cysteine nitrosylation, post-translational modifications, and interactions with proteins that bind either at the N- or C-terminus.
