Protein
Glutamate receptor ionotropic, NMDA 3A
Gene
Grin3a
Organism
Rattus norvegicus (Rat)
Status
Reviewed - Annotation score: 5 out of 5 - Experimental evidence at protein leveli

Functioni

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. May play a role in the development of dendritic spines. May also play a role in PPP2CB-NMDAR mediated signaling mechanism.

Interactioni

Subunit structurei

Forms heteromeric channel of a zeta subunit (GRIN1), a epsilon subunit (GRIN2A, GRIN2B, GRIN2C or GRIN2D) and a third subunit (GRIN3A or GRIN3B). Does not form functional homomeric channels. Found in a complex with GRIN1, GRIN2A or GRIN2B and PPP2CB. Probably interacts with PPP2CB. No complex with PPP2CB is detected when NMDARs are stimulated by NMDA.4 Publications
