Glutamate receptor, ionotropic kainate 5 is a protein that in humans is encoded by the GRIK5 gene. ^{[5] [6]}

Function

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. ^[6]

Interactions

GRIK5 has been shown to interact with DLG4 ^{[7] [8]} and GRIK2. ^{[9] [10]}
