Orexin receptor type 1 (Ox1R or OX1), also known as hypocretin receptor type 1 (HcrtR1), is a protein that in humans is encoded by the HCRTR1 gene. [5]
Function
The orexin 1 receptor (OX1), is a G-protein coupled receptor that is heavily expressed in projections from the lateral hypothalamus and is involved in the regulation of feeding behaviour. OX1 selectively binds the orexin-A neuropeptide. It shares 64% identity with OX2. [5]
