Recombinant Human Epiregulin (EREG)

Description

Epiregulin acts as a local signal mediator and shows dual biological activity, stimulating the proliferation of fibroblasts, hepatocytes, smooth muscle cells, and keratinocytes while also inhibiting the growth of several tumor-derived epithelial cell lines. Epiregulin was first identified in NIH 3T3 cell conditioned medium, and is one of the seven known ligands for the epidermal growth factor receptor EGFR . Epiregulin is synthesized as a transmembrane precursor before being proteolytically cleaved to release a 46-amino-acid active protein. Epiregulin also shows more potent bioactivity in vitro than other EGF-like growth factors
