Glutamate [NMDA] receptor subunit epsilon-2 is a protein that in humans is encoded by the GRIN2B gene.[1]

N-methyl-D-aspartate (NMDA) receptors are a class of ionotropic glutamate receptors. NMDA receptor 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). GRIN2B may be a candidate gene for the neurodegenerative disorder dentatorubral-pallidoluysian atrophy (DRPLA)[2]



GRIN2B has been shown to interact with LIN7B,[3] DLG4,[4][5][6][7][8][9] DLG2,[5][6] DLG3,[4][5][6][8] EXOC4,[4] RICS[10] and Actinin, alpha 2.[11]
