Orphan Receptor
A receptor identified through genomic or proteomic studies whose endogenous ligand and physiological function remain unknown. Deorphanization — identifying the natural ligand — can reveal new therapeutic targets. Many GPCRs, nuclear receptors, and ion channels were initially classified as orphans.
