Here, we show that the Paf1 complex (Paf1C) modulates Pol II elongation rate, and loss of Paf1 results in accumulation of Ser5P in the first 20 to 30 kb of gene bodies, coinciding with reduction of histone H2B ubiquitylation specifically ... WebRNA polymerase II (RNAPII) is a 12-subunit enzyme which synthesizes all mRNAs as well as several non-coding RNAs in eukaryotic cells thereby playing a central role in cellular functions. RNAPII is a DNA-dependent RNA polymerase enzyme which catalyzes the transcription of DNA into RNA employing four ribonucleoside triphosphates as substrates. champva provider billing manual
