Protein Structure

UniProt Annotation

Function

NMDA receptor subtype of glutamate-gated ion channels with reduced single-channel conductance, low calcium permeability and low voltage-dependent sensitivity to magnesium. Mediated by glycine.

Subcellular Localization

Cell membrane {ECO:0000250}; Multi-pass membrane protein {ECO:0000250}. Cell junction, synapse, postsynaptic cell membrane {ECO:0000250}. Note=Requires the presence of GRIN1 to be targeted at the plasma membrane. {ECO:0000250}.
