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].
