Rabbit polyclonal to AmphiregulinAmphiregulin binds to EGF Receptor (EGFR) with lower affinity than EGF. The mature secreted form AR is an 84 amino acid residue glycosylated polypeptide growth regulator, which is generated by proteolytic processing of a 252 amino acid transmembrane precursor. Seven different polypeptide ligands, which derive from distinct genes, are capable of binding to the extracellular domain of EGFR. These ligands include EGF, TGF alpha, AR, HB EGF, cripto 1, epiregulin, and betacellulin. All of these growth factors contain a characteristic EGF like domain which is defined by 6 evenly spaced cysteine residues that generate 3 loops through the formation of disulfide bonds. AR protein has been localized by immunohistochemistry to the epithelium of the colon, stomach, pancreas, breast, and placenta. AR is reportedly overexpressed in human cancers of breast, colon, stomach, and pancreas. |
