GRIN2D

GRIN2D

A gene on chromosome 19q13.33 that encodes an epsilon subunit of N-methyl-D-aspartate (NMDA) receptors, which belong to the glutamate receptor channel superfamily. NMDA receptors consist of multiple subunits arranged to form a ligand-gated ion channel, which play a key role in long-term potentiation and the plasticity of synapses (central to memory and learning). GRIN2D forms a complex with GRIN1, GRIN3A or GRIN3B; it interacts with PDZ domains of INADL and DLG4.
