Description

GPR43 is a GPCR that, along with GPR41, is activated by short chain carboxylic acids formate, acetate, proprionate, butyrate and pentanoate. Neutrophils and other leukocytes selectively express GPR43, and GPR43 mediates calcium flux and chemotaxis in these cells by coupling to both Gq and Gi (Brown et al., 2003, Le Poul et al., 2003). Millipore's GPR43 membrane preparations are crude membrane preparations made from our proprietary stable recombinant cell lines to ensure high-level of GPCR surface expression, thus, they are ideal HTS tools for screening of GPR43 interactions with its ligands. The cell line exhibits a calcium response with EC50s of 11.8muM for sodium propionate. The membrane preparations exhibit EC50s of 40.7 muM for sodium propionate in a GTPgammaS binding assay., Full-length human GPR43 cDNA
