Glutamate [NMDA] receptor subunit epsilon-1 is a protein that in humans is encoded by the GRIN2A gene. [5] With 1464 amino acids, the canonical GluN2A subunit isoform is large. GluN2A-short isoforms specific to primates can be produced by alternative splicing and contain 1281 amino acids. [6] [7]

Function

N-methyl-D-aspartate (NMDA) receptors are a class of ionotropic glutamate receptors. NMDA channel has been shown to be involved in long-term potentiation, an activity-dependent increase in the efficiency of synaptic transmission thought to underlie certain kinds of memory and learning. NMDA receptor channels are heteromers composed of the key receptor subunit NMDAR1 ( GRIN1) and 1 or more of the 4 NMDAR2 subunits: NMDAR2A (GRIN2A), NMDAR2B ( GRIN2B), NMDAR2C ( GRIN2C), and NMDAR2D ( GRIN2D). [8]

Associations

Variants of the gene are associated with the protective effect of coffee on Parkinson's disease. [9] [10]

Mutations in GRIN2A are associated to refractory epilepsy. [11]

Whole exome/genome sequencing has led to the discovery of an association between mutations in GRIN2A and a wide variety of neurological diseases, including epilepsy, intellectual disability, autism spectrum disorders, developmental delay, and schizophrenia. [12]

Interactions

GRIN2A has been shown to interact with:
