Grid2

Glutamate receptor, ionotropic, delta 2, also known as GluD2, GluRδ2, or δ 2 , is a protein that in humans is encoded by the GRID2 gene. This protein together with GluD1 belongs to the delta receptor subtype of ionotropic glutamate receptors. They possess 14–24% sequence homology with AMPA, kainate, and NMDA subunits, but, despite their name, have been found not to directly promote neuronal activation in response to glutamate or various other glutamate agonists. delta iGluRs have long been considered orphan receptors as their endogenous ligand was unknown. They are now believed to bind glycine and D-serine but these do not result in channel opening.
