Oreksinski receptor tip 2 (OX2R, OX2, ili hipokretinski receptor tip 2), je protein koji je kod ljudi kodiran HCRTR2 genom.[1]
Funkcija[uredi | uredi kod]
OX2 je G-protein spregnuti receptor koji je isključivo izražen u mozgu. On je 64% identičan s OX1. OX2 vezuje oreksin A i oreksin B neuropeptide. OX2 učestvuje u centralnom povratnom mehanizmu koji reguliše unos hrane.[1]
