Description
Description: DPH2 Human Recombinant produced in Sf9 Baculovirus cells is a single, glycosylated polypeptide chain containing 497 amino acids (1-489a.a.) and having a molecular mass of 53.1kDa (Molecular size on SDS-PAGE will appear at approximately 50-70kDa). DPH2 is expressed with an 8 amino acids His tag at C-Terminus and purified by proprietary chromatographic techniques.
Introduction: Diphthamide biosynthesis protein 2 (DPH2) is a homodimer and each of its monomers can bind a [4Fe-4S] cluster. DPH2 is the target of ADP ribosylating diphtheria toxin (DT) and Pseudomonas exotoxin A (PE). DPH2 was identified by its ability to complement a diphthamide mutant strain, and thus serves in diphthamide biosynthesis. The loss of DPH2 pre-activates NF-kB and death receptor pathways and renders MCF7 cells hypersensitive to tumor necrosis factor.
