Anti-Glutamate Receptor 4 Antibody

Approx. 100 kDa

Glutamate receptor 4 (UniProt: P48058; also known as GluR-4, GluR4, AMPA-selective glutamate receptor 4, GluR-D, Glutamate receptor ionotropic AMPA 4, GluA4) is encoded by the GRIA4 (also known as GLUR4) gene (Gene ID: 2893) in human. The postsynaptic actions of glutamate are mediated by a variety of receptors that are named according to their selective agonists. GluR-4 is a multi-pass membrane protein that functions as ligand-gated ion channel in the central nervous system and plays an important role in excitatory synaptic transmission. It displays greater affinity for AMPA. GluR-4 is synthesized with a signal peptide (aa 1-20), which is cleaved off in the mature form. GluR-4 can exist as a homotetramer or heterotetramer of pore-forming glutamate receptor subunits, tetramers can also form by the dimerization of dimers. GluR-4 is generally palmitoylated and becomes de-palmitoylated upon glutamate stimulation. Palmitoylation on Cys 611 leads to its Golgi retention and reduced cell surface expression. However, palmitoylation at Cys 837 does not affect cell surface expression, but can regulate stimulation-dependent endocytosis. GluR-4 can undergo phosphorylation at Serine 862 by PKC gamma and this phosphorylation increases plasma membrane-associated GRI4 expression.

Epitope: C-Terminus

Synthetic linear peptide.

Immunohistochemistry:
