Epiregulin / EREG蛋白背景綜述
Epiregulin, also known as EREG, is a secreted and a single-pass type I membrane protein which belongs to the epidermal growth factor family. Epiregulin / EREG contains one EGF-like domain. In normal *****s, Epiregulin / EREG is expressed predominantly in the placenta and peripheral blood leukocytes. High levels of Epiregulin / EREG were detected in carcinomas of the bladder, lung, kidney and colon. Epiregulin / EREG may be a mediator of localized cell proliferation. As a mitogen it may stimulate cell proliferation and / or angiogenesis. Epiregulin / EREG can function as a ligand of EGFR (epidermal growth factor receptor), as well as a ligand of most members of the ERBB (v-erb-b2 oncogene homolog) family of tyrosine-kinase receptors. The secondary structure at the C-terminus Epiregulin / EREG is different from other epidermal growth factor family ligands because of the lack of hydrogen bonds. The structural difference at the C-terminus may provide an explanation for the reduced binding affinity of epiregulin to the ERBB receptors.
