Glutamate receptor, ionotropic kainate 5 is a protein that in humans is encoded by the GRIK5 gene.[1][2]

Function[edit]

This gene encodes a protein that belongs to the glutamate-gated ionic channel family. Glutamate functions as the major excitatory neurotransmitter in the central nervous system through activation of ligand-gated ion channels and G protein-coupled membrane receptors. The protein encoded by this gene forms functional heteromeric kainate-preferring ionic channels with the subunits encoded by related gene family members.[2]

Interactions[edit]

GRIK5 has been shown to interact with DLG4[3][4] and GRIK2.[5][6]
