The eukaryotic RNA polymerase II (RNAPII) catalyzes the transcription of all protein encoding genes and is also responsible for the generation of small regulatory RNAs. RNAPII has evolved a unique domain composed of heptapeptide repeats with the consensus sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7 at the C-terminus (CTD) of its largest subunit (Rpb1).(More)
Dynamic modification of heptad-repeats with the consensus sequence Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7 of RNA polymerase II (RNAPII) C-terminal domain (CTD) regulates transcription-coupled processes. Mass spectrometry analysis revealed that K7-residues in non-consensus repeats of human RNAPII are modified by acetylation, or mono-, di-, and tri-methylation.(More)
Dynamic phosphorylation of Tyr1-Ser2-Pro3-Thr4-Ser5-Pro6-Ser7 heptad-repeats in the C-terminal domain (CTD) of the large subunit coordinates progression of RNA polymerase (Pol) II through the transcription cycle. Here, we describe an M phase-specific form of Pol II phosphorylated at Thr4, but not at Tyr1, Ser2, Ser5, and Ser7 residues. Thr4 phosphorylated(More)
Die C-terminale Domäne (CTD) der RNA-Polymerase II (RNAPII) ermöglicht die Transkription von Chromatin, koordiniert viele RNA-Reifungsschritte und ist wichtig für das Lesen und Schreiben epigenetischer Information. The carboxy-terminal domain (CTD) of RNA polymerase II (RNAPII) facilitates transcription of chromatin, coordinates diverse RNA maturation(More)
PeBoW, a trimeric complex consisting of pescadillo (Pes1), block of proliferation (Bop1), and the WD repeat protein 12 (WDR12), is essential for processing and maturation of mammalian 5.8S and 28S ribosomal RNAs. Applying a mass spectrometric analysis, we identified the DEAD-box helicase DDX27 as stably associated factor of the PeBoW-complex. DDX27(More)
