Détail du produit anti-Rpb1 CTD anticorps

Épitope: pTyr1

Fonction: RNA pol II CTD phospho Tyr1 antibody (mAb) (Clone 3D12)

Purification: Protein G Chromatography

Immunogène: This antibody was raised against a synthetic peptide containing the RNA Pol II heptad repeat consensus sequence phosphorylated at tyrosine 1.

Isotype: IgG1

Information d'application

Indications d'application: 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.

Détails sur Rpb1 CTD

Antigène: Rpb1 CTD (RNA Polymerase II CTD)

Autre désignation: RNA Pol II CTD

Sujet: 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.
