Background and Alternate Names
Human G-protein coupled receptor 183 (GPR183), is a 7-transmembrane G protein-coupled receptor (GPCR). It is a Class A GPCR. GPR183 is expressed on the surface of some immune cells, namely B cells and T cells. GPR183 is a receptor for oxysterols. GPR183 is a critical mediator of immune cell localization within lymph nodes. GPR183-expressing cells are attracted to locations of high oxysterol ligand concentration. During severe viral respiratory infections such as influenza A virus (IAV) and SARS-CoV-2, GPR183 plays a critical role in driving inflammation in the lungs. Human GPR183 protein has >90% sequence homology with mouse GPR183.
