Grin2a - glutamate ionotropic receptor NMDA type subunit 2A

Enables several functions, including enzyme binding activity; glutamate binding activity; and ligand-gated ion channel activity. Contributes to cation channel activity and extracellularly glutamate-gated ion channel activity. Involved in several processes, including cellular response to metal ion; central nervous system development; and modulation of chemical synaptic transmission. Located in several cellular components, including dendritic spine; postsynaptic density; and synaptic membrane. Is integral component of plasma membrane. Part of NMDA selective glutamate receptor complex. Is active in glutamatergic synapse and parallel fiber to Purkinje cell synapse. Is integral component of presynaptic membrane. Used to study hyperhomocysteinemia. Biomarker of cognitive disorder; placental insufficiency; and status epilepticus. Human ortholog(s) of this gene implicated in Huntington's disease; bipolar disorder; and schizophrenia. Orthologous to human GRIN2A (glutamate ionotropic receptor NMDA type subunit 2A).
