OX1 receptors are G protein-coupled receptors whose orthologs are present throughout mammals. OX1 expression in CNS includes brainstem nuclei involved in arousal and sleep/wake regulation as well as nuclei involved in reward signaling. Orexin-A and -B neuropeptides have different affinities for OX1 receptors (IC50s of 20 and 420 nM, respectively). Receptor activation results in elevated intracellular calcium levels mediated by Gq and phospholipase C activation, but contributions from Gs- and Gi-mediated regulation of cAMP levels as well as non-selective cation channels have also been described. OX1 receptor signaling in sleep/wake regulation is not as well defined as for OX2 receptors, but has been implicated in mood, anxiety, memory and reward, with mixed effects on feeding reported. OX1 receptor desensitization, β-arrestin recruitment and internalization are regulated by phosphorylation of carboxyl-terminal serine385(pS385-OX1), serine393/serine394 (pS393/pS394-OX1) and serine399/serine401 (pS399/pS401-OX1). This nomenclature refers to the human OX1. This phosphorylation motif is conserved across species but corresponds to pS384/pS385-OX1 and pS390/pS392-OX1 in mice and rats.
