Oksitocinski receptor, ili OXTR, je protein koji dejstvuje kao receptor za hormon i neurotransmiter oksitocin.[1][2] Kod ljudi, oksitocinski receptor je kodiran OXTR genom.[3][4], koji je lokalizovan na ljudskom hromozomu 3p25.[5]

Funkcija i lokacija

OXTR protein pripada familiji G-protein spregnutih receptora, specifično Gq,[1] i dejstvuje kao receptor za oksitocin. Njegova aktivnost je posredovana G proteinima koji aktiviraju više različitih sistema sekundarnih glasnika.[6][7]

Oksitocinski receptori su izraženi u mioepitelijalnim ćelijama mlečnih žlezdi, i u miometrijumu i endometrijumu uterusa na kraju trudnoće. Sistem oksitocina ima važnu ulogu indukovanja uterinskih kontrakcija tokom porođaja i izbacivanja mleka.

Oksitocinski receptori su takođe prisutni u centralnom nervnom sistemu. Ti receptori modulišu više odlika ponašanja, poput stresa i anksioznosti, socijalne memorije i prepoznavanja, seksualnog i agresivnog ponašanja, druženja (afilijacije) i materinskog ponašanja.[8][9][10]

Ko nekih sisara, oksitocinski receptori su takođe nađeni u bubrezima i srcu.

Ligandi

Nekoliko selektivnih liganda oksitocinskih receptora je nedavno bilo razvijeno, ali značajna sličnost između oksitocinskog i srodnog vazopresinskog receptora onemogućava visoku selektivnost.[11][12]
