Descrizione generale

RNA polymerase II (RNAPII or Pol II) is a multi-subunit enzyme responsible for the transcription of transcription of DNA into RNA from protein-coding genes. Transcription initiation requires recruitment of the complete transcription machinery to a promoter via solicitation by activators and chromatin remodeling factors. RNAPII can coordinate 10 to 14 subunits. This complex interacts with the promoter regions of genes and a variety of elements and transcription factors. The DNA binding domain of the polymerase is a groove where TFIIB orients the DNA for unwinding and transcription. As the study of the RNA polymerase II (RNAPII) transcription complex expands, many researchers are interested in using immunoblots to detect RNAPII in various protein preparations and column fractions. HeLa cell RNAPII contains 10 subunits, the largest possessing a heptapeptide repeat (PTSPSYS) in the C-terminal domain (CTD). This large subunit cycles, during the course of transcription, through nonphosphorylated (RNAPIIA) and hyperphosphorylated (RNAPIIO) forms. RNAPIIA associates with the basal transcription complex and becomes phosphorylated to the RNAPIIO form before the synthesis of the first phosphodiester bond. The timing of these events suggests that this phosphorylation event may function as a regulatory point, and there is considerable interest in identifying components of the transcription complex with CTD kinase activity.
