Peptid oslobađanja gastrina (GRP) je regulatorni molekul koji učestvuje u brojnim fiziološkim i patofiziološkim procesima. Najbolje poznato dejstvo ovog peptida je stimulacija oslobađanja gastrina iz G ćelija želuca.

Gen iz kojeg je GRP izveden kodira brojne peptide slične bombesinu.^[1]^[2]^[3]^[4] Njegov 148-aminokiselina dug preproprotein, nakon odvajanja signalnog peptida, se dalje transformiše da bi se formirao bilo 27 aminokiselina dug peptid oslobađanja gastrina ili 10 aminokiselina dug neuromedin C. Ovi manji peptidi regulišu brojne funkcije gastrointestinalnog i centralnog nervnog sistema, uključujući otpuštanje gastrointestinalnih hormona, kontrakciju ćelija glatkih mišića, i proliferaciju epitelijalnih ćelija.^[1]
