DNA-directed RNA polymerase II subunit RPB11-a (POLR2J)

DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Component of RNA polymerase II which synthesizes mRNA precursors and lots of functional non-coding RNAs.

Pol II is the central part of the basal RNA polymerase II transcription machinery. It's composed of mobile elements that move relative to one another.
