Beschreibung

General description

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.

~270 kDa observed. Uncharacterized band(s) may be observed in some cell lysates. This protein may be observed at higher molecular weights due to post-translational modification.
