Room temperature in continental US; may vary elsewhere.


The human epiregulin gene encoded a 163-residue putative transmembrane precursor containing an EGF-like domain in the internal segment, and the structural organization was similar to that of other members of the EGF family that bind to EGF receptors. Epiregulin has certain characteristics that are different from those of the classical members of the EGF family, EGF and transforming growth factor alpha, including mitogenic responses on several normal cells and binding to EGF receptors on epidermoid carcinoma A431 cells. Northern blot analysis shows the expression of human epiregulin to be mainly on peripheral blood macrophages and the placenta in normal tissues, and is highest on epithelial tumour cell lines in various types of tumour cell lines. Epiregulin is involved in certain physiological processes such as maintenance or development of normal cell growth, and the progression of carcinomas[1].
