8WG16_Purified_RPB1_Antibody_1_WB_082316
Total lysates (15 µg protein) from HeLa cells were resolved by electrophoresis (4-12% Bis-Tris gel), transferred to nitrocellulose, and probed with 1:500 diluted (1 µg/mL) Purified anti-RNA Polymerase II RBP1 Antibody, clone 8WG16 (upper) or 1:3000 diluted Purified anti-β-actin Antibody, clone Poly6221 (lower). Proteins were visualized by chemiluminescence detection using a 1:3000 diluted goat anti-mouse-IgG secondary antibody conjugated to HRP for the anti-RNA Polymerase II RBP1 Antibody, and a donkey anti-rabbit IgG Antibody conjugated to HRP for anti-β-actin Antibody.

    HeLa cells were fixed with 2% paraformaldehyde (PFA) for ten minutes, permeabilized with 0.5% Triton X-100 for five minutes, and blocked with 5% FBS for 30 minutes. Then the cells were intracellularly stained with 2 µg/ml anti-RNA Polymerase II RPB1 (clone 8WG16 ) in blocking buffer overnight at 4°C and followed by DyLight™ 594 (red) conjugated goat anti-mouse IgG for one hour at room temperature. Actin filaments were labeled with Alexa Fluor® 488 Phalloidin (green). Nuclei were counterstained with DAPI (blue). The image was captured with a 60X objective.

    Chromatin Immunoprecipitations (ChIP) were performed with cross-linked chromatin samples from 4 X 106 of HeLa cells with either A)1:300 dilution of Go-ChIP-Grade™ Purified anti-RNA Polymerase II RPB1 Antibody (clone 8WG16, Cat. No. 664911) or B) equal amount of Purified Mouse IgG2a, κ Isotype Control Antibody (Clone MOPC-173, Cat. No. 400201) by using Go-ChIP-Grade™ Protein G Enzymatic Kit (Cat. No. 699904). The enriched DNA was purified and quantified by real-time qPCR using primers targeting human GAPDH gene region and α-Satellite repeats. The amount of immunoprecipitated DNA in each sample is represented as signal relative to total amount of input chromatin.

Description

RPB1 is the catalytic and largest component of RNA polymerase II, which synthesizes mRNA precursors and many functional non-coding RNAs. It forms the polymerase active center together with RPB2, the second largest subunit. Polymerase II (Pol II) is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relatively to each other. RPB1 is part of the core element with the central large cleft, the clamp element that moves to open and close the cleft, and the jaws that are thought to grab the incoming DNA template. At the start of transcription, a single DNA template strand of the promoter is positioned within the central active site cleft of Pol II. Then, a bridging helix emanates from RPB1 and crosses the cleft near the catalytic site, which acts as a ratchet that moves the RNA-DNA hybrid through the active site by switching from straight to bent conformations during each neuocleotide addition. This promotes translocation of Pol II. Pol II moves on the template during transcription elongation. Elongation is influenced by the phosphorylation status of the C-terminal domain (CTD) of Pol II's largest subunit (RPB1), which serves as a platform for assembling factors that regulate transcription initiation, elongation, termination, and mRNA processing. It can act as a RNA-dependent RNA polymerase when associated with small delta antigen of Hepatitis delta virus, being able to conform as both a replicate and transcriptase for the viral RNA circular genome.
