Characteristics: Anti-GPR4 (extracellular) Antibody (ABIN7043160, ABIN7044423 and ABIN7044424) is a highly specific antibody directed against an epitope of the rat protein. The antibody can be used in western blot and indirect live cell flow cytometry applications. The antibody recognizes an extracellular epitope and is thus ideal for detecting the receptor in living cells. It has been designed to recognize GPR4 from mouse, rat, and human samples.

Purification: Affinity purified on immobilized antigen.

Target Details for GPR4

Target: GPR4 (G Protein-Coupled Receptor 4 (GPR4))

Alternative Name: GPR4

Background: Acid-sensing G-protein coupled receptor 4, GPR19,G-protein coupled receptor 4 (GPR4) belongs to a protein family comprised of 3 related G-protein coupled receptors (GPCRs): GPR4, OGR1/GPR68 and TDAG8/GPR65. Like all GPCRs, GPR4's structure is composed of seven-transmembrane-spanning domains linked by an N-terminal extracellular domain and a C-terminal intracellular domain2.GPR4 responds to pH changes and is activated by a physiological increase in extracellular H+ through several signaling pathways including- the G12/13-protein/Rho, the Gq/PLC, and the Gs-protein/cAMP pathway1,2. It is fully activated at pH levels of 6.8 and lower and is inactive at pH levels of 7.5 and higher3,4.Recent studies show that the pH -sensing GPCRs also have the ability to regulate cancer cell metastasis and proliferation, immune cell function, inflammation, blood vessel formation, endothelial barrier function thus making them an important therapeutic target for different diseases. Overexpression of GPR4 in human cancer cells shows involvement in driving or maintaining tumor formation.GPR4 is expressed in several tissues including lung, vascular endothelial cells, kidney, heart, liver, skeletal muscle, ovary, and placenta.
