Recombinant human Betacellulin protein
BTC (Betacellulin) is a member of the EGF family of growth factors and contains 1 EGF-like domain. It is synthesized primarily as a transmembrane precursor, which is then processed to mature molecule by proteolytic events. This protein is a ligand for the EGF receptor. The effects of BTC are probably mediated by the EGF receptor and other related receptors. Recombinant human BTC protein, fused to His-tag at N-terminus, was expressed in E. coli and purified by using conventional chromatography techniques.
