REXO1 Recombinant Protein

Source : Escherichia Coli. REXO1 Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 198 amino acids (1060-1221a.a) and having a molecular mass of 22.3kDa. REXO1 is fused to a 36 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. REXO1 is an exonuclease domain-containing protein which binds to Elongin. The Elongin complex stimulates the rate of transcription elongation by RNA polymerase II by suppressing the transient pausing of the polymerase at many sites along the DNA template. REXO1 is composed of 1221 amino acids and its mRNA is ubiquitously expressed. REXO1 is a putative stem cell marker and is highly expressed in embryonic and adult stem cells.
