概述

Amphiregulin is an EGF related growth factor and was originally isolated from the conditioned media of a PMA-treated MCF-7 human breast carcinoma cell line.It is mainly expressed numerous carcinoma cell lines and the epithelial cells of various human tissues including colon,stomach,breast,ovary,kidney,etc.Synthesized as a transmembrane protein,Amphiregulin’s extracellular domain is proteolytically processed to release the mature protein.There are 6 conserved cysteine residues,which form 3 intramolecular disulfide bonds essential for biological activity.Amphiregulin signals through the EGF/TGF-a receptor,and stimulates growth of keratinocytes,epithelial cells and some fibroblasts.It also inhibits the growth of certain carcinoma cell lines.Mutations in this encoded protein are associated with a psoriasis-like skin phenotype.
