Orexin R1/HCRTR1: Proteins and Enzymes

HCRTR1, or orexin 1 receptor (OX1R), is a G-protein coupled receptor expressed in the hypothalamus and involved in the regulation of feeding behaviour. HCRTR1 selectively binds the orexin A neuropeptide. It shares 64% identity with HCRTR2. [provided by RefSeq]
