Rabbit anti-Human GRPR Polyclonal Antibody

Uniprot Id

P30550

Target Species

Human

Target Name

GRPR

Target Full Name

Gastrin-releasing peptide receptor

Target Function

Receptor for gastrin-releasing peptide (GRP). Signals via association with G proteins that activate a phosphatidylinositol-calcium second messenger system, resulting in Akt phosphorylation. Contributes to the regulation of food intake. 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. Contributes primarily to nonhistaminergic itch sensation. Contributes to long-term fear memory, but not normal spatial memory.

Target Subcellular Location

Cell membrane; Multi-pass membrane protein.

Target Protein Families

G-protein coupled receptor 1 family

Target Tissue Specificity

Highly expressed in pancreas. Also expressed in stomach, adrenal cortex and brain.

Target Research Area

Neuroscience

Target Synonyms

BB2; Bombesin BB2 receptor; bombesin receptor 2; Gastrin Releasing Peptide Receptor; Gastrin-releasing peptide receptor; GRP preferring bombesin receptor; GRP R; GRP-preferring bombesin receptor; GRP-R; Grp/bombesin receptor; Grpr; GRPR_HUMAN

Target Background

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.
