G-protein coupled receptor family C group 6 member A (GPRC6A, GPCR33) (Wellendorph P and Brauner-Osborne H, 2004) is a receptor that functions as a sensor for both L-amino acids and extracellular concentration of calcium ions. GPRC6A is a promiscuous L-alpha-amino acid receptor but has preference for the basic amino-acids L-Arg, L-Lys and L-ornithine (Wellendorph P et al, 2005). The effects of this receptor are mediated by coupling to the G protein alpha q/11 subunit, which activates a phosphatidylinositol-calcium second messenger system.
