5-HT4 receptor (5-hidroksitriptaminski receptor 4) je protein koji je kod ljudi kodiran HTR4 genom.^[1]^[2]

Ovaj gen je član familije serotoninskih receptora, koji su G protein spregnuti receptori koji stimulišu cAMP produkciju u responsu na vezivanje serotonina (5-hidroksitriptamina). To je glikolizirani transmembranski protein koji funkcioniše u perifernom i centralnom nervnom sistemu gde modulara otpuštanje raznih neurotransmitera. Postoji više transkriptnih varijanti koje kodiraju proteine sa distinktnim C-terminalnim sekvencama.^[3]

Lokacija уреди

Receptor je lociran u alimentarnom traktu, mokraćnoj bešiki, srcu i nadbubrežnoj žlezdi, kao i u centralnom nervnom sistemu (CNS).^[4] On nije nađen u cerebelumu.^[5]

Izoforme уреди

Internalizacija je specifična za pojedine izoforme.^[6]

Ligandi уреди

Postoji nekoliko lekova kaji deluju na 5-HT₄ kao selektivni agonisti. Oni se koriste u naučnim istraživanjima i kliničkoj medicini. Neki od lekova koji deluju kao 5-HT₄ agonisti su isto tako aktivni kao 5-HT₃ antagonisti, npr, mosaprid, metoclopramid, renzaprid i zacoprid.^[7] SB-207,145 radio obeležen sa ugljenikom-11 se koristi kao radioligand za 5-HT₄ ispitivanja pozitronskom emisionom tomografijom na životinjama^[8] i u humanim ispitivanjima.^[9].
