GRIK5 Antibody – Rabbit Polyclonal

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. [provided by RefSeq, Jul 2008]

GluR KA2: Receptor for glutamate. L-glutamate acts as an excitatory neurotransmitter at many synapses in the central nervous system. The postsynaptic actions of Glu are mediated by a variety of receptors that are named according to their selective agonists. This receptor binds kainate > quisqualate > domoate > L- glutamate >> AMPA >> NMDA = 1S,3R-ACPD. Belongs to the glutamate-gated ion channel (TC 1.A.10.1) family. GRIK5 subfamily. 2 isoforms of the human protein are produced by alternative splicing.
