Oreksinski receptor tip 1 (OX1R, OX1, ili hipokretinski receptor tip 1), je protein koji je kod ljudi kodiran HCRTR1 genom.[1]
Funkcija
OX1 je G-protein spregnuti receptor koji je izražen u hipotalamusu i učestvuje u regulaciji ishrane. OX1 selektivno vezuje neuropeptid oreksin-A. On je 64% identičan sa OX2.[1]
