Amphiregulin
Lua error in Module:Infobox_gene at line 33: attempt to index field 'wikibase' (a nil value). Amphiregulin, also known as AREG, is a protein that in humans is encoded by the AREG gene.[1][2][3]
Function
The protein encoded by this gene is a member of the epidermal growth factor (EGF) family.[1]
It is an autocrine growth factor as well as a mitogen for astrocytes, Schwann cells, fibroblasts. It is related to epidermal growth factor (EGF) and transforming growth factor alpha (TGF-alpha). This protein interacts with the Epidermal growth factor receptor (EGFR) to promote the growth of normal epithelial cells.
Biological role
Estradiol and progesterone mostly induce amphiregulin expression to mediate ductal development of the mammary glands.[4][5][6][7][8] Amphiregulin has been found to be essential for mammary ductal development, as evidenced by absence of ductal growth in amphiregulin knockout mice.[7] This is similar to the phenotypes of EGFR and ERα knockout mice, which also show absence of ductal growth.[7]
Clinical signficance
Mutations in this encoded protein are associated with a psoriasis-like skin phenotype.[1]
