  2. RNA polymerase II - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase_II

    RNA polymerase II holoenzyme is a form of eukaryotic RNA polymerase II that is recruited to the promoters of protein-coding genes in living cells. [11] It consists of RNA polymerase II, a subset of general transcription factors , and regulatory proteins known as SRB proteins.

  3. RNA polymerase II holoenzyme - Wikipedia

    en.wikipedia.org/wiki/RNA_polymerase_II_holoenzyme

    RNA polymerase II (also called RNAP II and Pol II) is an enzyme found in eukaryotic cells. It catalyzes the transcription of DNA to synthesize precursors of mRNA and most snRNA and microRNA . [ 3 ] [ 4 ] In humans, RNAP II consists of seventeen protein molecules (gene products encoded by POLR2A-L, where the proteins synthesized from POLR2C ...

  6. Promoter (genetics) - Wikipedia

    en.wikipedia.org/wiki/Promoter_(genetics)

    The promoter is recognized by RNA polymerase and an associated sigma factor, which in turn are often brought to the promoter DNA by an activator protein's binding to its own DNA binding site nearby. In eukaryotes The process is more complicated, and at least seven different factors are necessary for the binding of an RNA polymerase II to the ...

  8. P-TEFb - Wikipedia

    en.wikipedia.org/wiki/P-TEFb

    The positive transcription elongation factor, P-TEFb, is a multiprotein complex that plays an essential role in the regulation of transcription by RNA polymerase II (Pol II) in eukaryotes. [1] Immediately following initiation Pol II becomes trapped in promoter proximal paused positions on the majority of human genes (Figure 1).

    en.wikipedia.org/wiki/RNA_polymerase_II_subunit_B4

    DNA-directed RNA polymerase II subunit RPB4 is an enzyme that in humans is encoded by the POLR2D gene. [ 5 ] This gene encodes the fourth-largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes.
