POLR2F Recombinant Protein

Source : E.coli. POLR2F Human Recombinant produced in E.coli is a single, non-glycosylated polypeptide chain containing 150 amino acids (1-127) and having a molecular mass of 16.9kDa (Molecular size on SDS-PAGE will appear higher) .POLR2F is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Polymerase II Polypeptide F (POLR2F) is the 6th largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes, which is also shared by the other two DNA-directed RNA polymerases. In yeast, POLR2F, in combination with at least 2 other subunits, forms a structure which stabilizes the transcribing polymerase on the DNA template. DNA-dependent RNA polymerases catalyze the transcription of DNA into RNA via the 4 ribonucleoside triphosphates as substrates. Pol II is the principal element of the basal RNA polymerase II transcription apparatus. Pols are comprised of mobile elements which move close to each other. In Pol II, POLR2F/RPB6 is part of the clamp element and along with parts of RPB1 and RPB2 constructs a compartment to which the RPB4-RPB7 subcomplex attaches.
