Receptor gastričnog inhibitornog polipeptida (GIP-R, glukozno zavisni insulinotropni polipeptidni receptor) je protein koji je kod ljudi kodiran GIPR genom.[1][2] GIP-R je sedam transmembranski protein prisutan u beta ćelijama u pancreasu.[3][4]

Funkcija[uredi - уреди | uredi kôd]

Gastrični inhibitorni polipeptid (GIP, glukozno zavisni insulinotropni polipeptid) je 42 aminokiseline dug polipeptid koji sintetišu K ćelije dvanaestopalačnog i tankih creva. On je originalno identifikovan kao sastojak stomačnog ekstrakta koji inhibira sekreciju želudačne kiseline i oslobađanje gastrina, ali je naknadno pokazano da potentno stimuliše otpuštanje insulina u prisustvu povišenih nivoa glukoze. Insulinotropno dejstvo na pankreasne beta ćelije je stoga njegova glavna fiziološka uloga. Zajedno sa glukagonu sličnim peptidom-1, GIP je u velikoj meri odgovoran za sekreciju insulina nakon jela. On učestvuje u nekoliko različitih oblika anaboličkog otpuštaja.[1]
