| 免疫原 | This RNA pol II CTD phospho Ser7 antibody was raised against a peptide containing the RNA pol II CTD sequence phosphorylated at serine 7. |
| 背景 | 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 two sites within the heptapeptide repeat, at serine 2, serine 5 and serine 7. RNA pol II Serine 7 phosphorylation is confined to promoter regions and is necessary for the initiation of transcription. |

RNA pol II CTD phospho Ser7 antibody (mAb) tested by ChIP-Seq. ChIP was performed using the ChIP-IT® High Sensitivity Kit (Cat. No. 53040) with chromatin from 2.3 million HL-60 cells and 4 ul of antibody. ChIP DNA was sequenced on the Illumina HiSeq and 20 million sequence tags were mapped to identify Pol II phospho Ser7 binding. The image shows a 350,000 base pair region on chromosome 1 with the expected enrichment at gene promoters. |
