Function
Receptor for gastrin-releasing peptide (GRP) (PubMed:1671171, PubMed:1707129, PubMed:9345264, PubMed:12526815, PubMed:26658875). Signals via association with G proteins that activate a phosphatidylinositol-calcium second messenger system, resulting in Akt phosphorylation (PubMed:26658875). Contributes to the regulation of food intake (PubMed:12176666). Contributes to the perception of prurient stimuli and transmission of itch signals in the spinal cord that promote scratching behavior, but does not play a role in the perception of pain (PubMed:28280205, PubMed:17653196, PubMed:26658875). Contributes primarily to nonhistaminergic itch sensation (PubMed:28280205). Contributes to long-term fear memory, but not normal spatial memory (PubMed:12526815).
