Grin3a - glutamate ionotropic receptor NMDA type subunit 3A

Enables several functions, including glycine binding activity; ionotropic glutamate receptor activity; and protein phosphatase 2A binding activity. Contributes to NMDA glutamate receptor activity. Involved in several processes, including calcium ion transport; ionotropic glutamate receptor signaling pathway; and negative regulation of dendritic spine development. Located in postsynaptic membrane. Part of NMDA selective glutamate receptor complex. Is active in glutamatergic synapse. Is integral component of postsynaptic density membrane. Orthologous to human GRIN3A (glutamate ionotropic receptor NMDA type subunit 3A). [provided by Alliance of Genome Resources, Apr 2022]
