RNA polymerase II 14.5 kDa subunit
RNA polymerase II subunit B9
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 many functional non-coding RNAs. Pol II is the central component of the basal RNA polymerase II transcription machinery. It is composed of mobile elements that move relative to each other. RPB9 is part of the upper jaw surrounding the central large cleft and thought to grab the incoming DNA template.
Belongs to the archaeal rpoM/eukaryotic RPA12/RPB9/RPC11 RNA polymerase family. Contains 1 TFIIS-type zinc finger.
Phosphorylated upon DNA damage, probably by ATM or ATR.
