Gastrin-releasing peptide receptor

The gastrin-releasing peptide receptor (GRPR), now properly known as BB2 [1] is a G protein-coupled receptor whose endogenous ligand is gastrin releasing peptide.[2] In humans it is highly expressed in the pancreas and is also expressed in the stomach, adrenal cortex and brain.[3]
Gastrin-releasing peptide (GRP) regulates numerous functions of the gastrointestinal and central nervous systems, including release of gastrointestinal hormones, smooth muscle cell contraction, and epithelial cell proliferation and is a potent mitogen for neoplastic tissues. The effects of GRP are mediated through the gastrin-releasing peptide receptor. This receptor is a glycosylated, 7-transmembrane G-protein coupled receptor that activates the phospholipase C signaling pathway. The receptor is aberrantly expressed in numerous cancers such as those of the lung, colon, and prostate. An individual with autism and multiple exostoses was found to have a balanced translocation between chromosome 8 and a chromosome X breakpoint located within the gastrin-releasing peptide receptor gene.[4]
The transcription factor CREB is a regulator of human GRP-R expression in colon cancer.[5]
