General Comments
GlyT1 has ben localized to glutamatergic synapses where it forms a physical interaction with the NMDA receptor-associated scaffolding protein PSD-95 (DLG4; P78352) [4]. Because of its essential role in NMDA receptor function GlyT1 inhibition is being actively pursued as a novel pharmacological intervention for the treatment of schizophrenia, a disease that is associated with impaired (hypofunctional) NMDA-mediated neurotransmission.
