Funkcija

Ovaj gen pripada familiji gena koji dejstvuju kao receptori za tahikinine. Receptorski afiniteti su određeni varijacijama 5'-kraja sekvence. Receptori iz ove familije su interaguju sa G proteinima i sadrže 7 hidrofobnih transmembranskih regiona. Ovaj gen kodira receptor za tahikinin neurokinin 3, koji je takođe poznat kao neurokinin B.

Selektivni ligandi

Nekoliko selektivnih liganda je dostupno za NK₃, pri čemu su dva jedinjenja: osanetant i talnetant u kliničkim ispitivanjima za lečenje šizofrenije i drugih indikacija.

Agonisti

• Senktid - 7-aminokiselinski polipeptid, NK₃ selektivan

Antagonisti

• Osanetant
• Talnetant
• SB-222,200 - potentan i selektivan antagonist, K_i = 4.4 nM, 3-Metil-2-fenil-N-[(1S)-1-fenilpropil]-4-hinolinkarboksamid
• SB-218,795 - selektivniji od SB-222,200, K_i = 13 nM, (R)-[(2-fenil-4-hinolinilkarbonil)amino]-metil ester benzensirčetna kiselina
