The G protein-coupled receptor (GPCR) kinase 2, GRK2, is a ubiquitous serine/threonine protein kinase that is able to phosphorylate and desensitize the active form of several GPCR. Compelling, as yet limited, evidence from in vitro studies have suggested a potential role of GRK2 in mediating desensitization of Gpr54, the canonical receptor for kisspeptins that is abundantly expressed in GnRH neurons. Yet, although kisspeptins have been universally recognized as essent...
