RNA polymerase II initiates a chemical reaction. It works by first opening a section of a DNA molecule. It then unwinds and pulls apart the DNA double helix, splitting it into two strands in a manner similar to unzipping a zipper. Then the polymerase allows for transcription, or copying, of all of the mRNA molecules inside a cell.

RNA polymerase II (Pol II) is the central enzyme that catalyses DNA- directed mRNA synthesis during the transcription of protein-coding genes. Pol II consists of a 10-subunit catalytic core, which alone is capable of elongating the RNA transcript, and a complex of two subunits, Rpb4/7, that is required for transcription initiation. The transcription cycle is divided in three major phases. Das Enzym RNA Polymerase II, kurz Pol II, ist verantwortlich für die Transkription (Abschrift eines Genabschnittes).

  1. clear RNAs are transcribed by RNA polymerase II (pol II). However, early attempts to reproduce mRNA transcrip- tion in vitro established that purified pol II alone was not capable of specific initiation (Roeder 1976; Weil et al. 1979). Selective initiation was achieved only when the polymerase was supplemented with a number of addi- tional protein components that could be isolated from crude.

  3. RNA polymerase II pausing could be an issue in this region. The difference between Pol II occupancy measurements at +200- to +400 vs. those at 0 to +100 is very subtle. In both cases, the Warfield et al. analysis of all genes shows very little difference between TATA-containing and TATA-less promoters, whereas our analysis of the 500 most well-expressed genes (i.e. the ones where there.

RNA polymerase II (Pol II) is the only polymerase to possess heptapeptide repeats in the C-terminal domain (CTD) of its large subunit. During transcription, CTD phopshorylation occurs and is maintained from initiation to termination.

RNA polymerase II elongation complex is predominant in the elongation stage during which the subunits of Pol II, which include secondary structures such as beta sheets, alpha helices, 3/10 helices and random coils, are able to unwind the DNA strand into its sense and nonsense strand, bind to the template DNA strand and synthesize a complementary mRNA strand We further demonstrate that RNA Polymerase II pausing is highly correlated with transcriptional repression, with elongation competent RNA polymerase II becoming a scare resource in late stage erythroblasts, allocated to erythroid-specific genes. Functional studies confirmed an essential role for maturation stage-specific regulation of RNA polymerase II activity during erythroid maturation.
