Application Details

Application Notes: WB*: 1 - 2 μg/mL *Note: Many chromatin-bound proteins are not soluble in a low salt nuclear extract and fractionate to the pellet. Therefore, we recommend a High Salt / Sonication Protocol when preparing nuclear extracts for Western blot. In addition, we recommend the addition of 0.05 % Tween 20 to all blocking solutions to reduce background. This antibody is also available as an AbFlex engineered recombinant antibody. For details on the corresponding AbFlex Recombinant Antibody, see Catalog No. 91219.

Target: POLR2F (Polymerase (RNA) II (DNA Directed) Polypeptide F (POLR2F))

Alternative Name: RNA pol II

Background:

Background_Plain: RNA pol II (RNA polymerase II) is responsible for synthesizing messenger RNA in eukaryotes. RNA pol II contains a carboxy terminal domain composed of heptapeptide repeats that are essential for polymerase activity. These repeats contain serine and threonine residues that are phosphorylated in actively transcribing RNA polymerase. In addition, RNA pol II, in combination with several other polymerase subunits, form the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA. During the transcription cycle, the CTD of the large subunit of RNA pol II is reversibly phosphorylated. RNA pol II containing unphosphorylated CTD is recruited to the promoter, whereas the hyperphosphorylated CTD form is involved in active transcription. Phosphorylation occurs at sites within the heptapeptide repeat, at serine 2, serine 5, serine 7 and tyrosine 1. RNA pol II Tyrosine 1 phosphorylation is found during elongation and appears to activate transcription by suppressing RNA pol II termination.
