Oksitocinski receptor, znan i kao OXTR, jest protein koji je kod ljudi kodiran genom OXTR sa hromosoma 3. Funkcionira kao receptor za hormone i neurotransmiter oksitocin.^[4]^[5]^[6]^[7]^[8]

Funkcija i lokacija uredi

OXTR protein pripada porodici G-protein spregnutih receptora, konkretno G_q,^[4] i djeluje kao receptor za oksitocin. Njegovu aktivnost posreduje G-protein koji aktivira nekoliko različitih sistema drugog glasnika.^[11]^[12]

Oksitocinski receptori se eksprimiraju u mioepitelnim ćelijama mliječnim žlijezdama, i u miometriju i endometriju maternice na kraju trudnoća. Sistem receptora oksitocin-oksitocin ima važnu ulogu kao induktor kontrakcija maternice tokom porođaja i izbacivanja mlijeka.

OXTR je također povezan sa centralnim nervnim sistemom. Vjeruje se da gen ima glavnu ulogu u društvenom, kognitivnom i emocijskom ponašanju.^[13] Vjeruje se da je povećanje ekspresije ovog gena povezano s neemocijskim osobinama, grubim razmišljanjem i problemima s prepoznavanjem lica i emocija. Također se vjeruje i da smanjenje ekspresije ovog gena dovodi do prenatalnog stresa, postnatalne depresije i socijalne anksioznosti.^[13] Moraju se obaviti dalja istraživanja prije zaključivanja ovih nalaza,ali jaki dokazi upućuju u tom smjeru . OXTR je također u snažnoj korelaciji s amigdalom i odgovorima povezanim sa strahom. Studije sugeriraju da metilacija OXTR-a, koja smanjuje regulaciju oksitocinskih mehanizama, rezultira povećanjem sive tvari u amigdali, što se dalje povezuje sa smanjenjem parasimpatičkog tonusa.^[14]

Kod nekih sisara, oksitocinski receptori se također nalaze u bubrezima i srcu.
