Data Sheet
Background: GPR132 (also known as G2A) is a proton-sensing receptor that is broadly expressed in the appendix, lymph nodes and other tissues. It may also be a receptor for oxidized free fatty acids. It appears to play a role in regulating certain cells of the autoimmune system by responding to the extracellular acidification characteristic of tissues suffering from malignant cell growth or inflammation
Application: Functional assays
