Target data

Background This gene encodes the second largest subunit of RNA polymerase II (Pol II), a DNA-dependent RNA polymerase that catalyzes the transcription of DNA into precursors of mRNA, snRNA and microRNA. This subunit and the largest subunit form opposite sides of the center cleft of Pol II. Deletion of the flap loop region of this subunit results in a decrease in the rate of transcriptional elongation. Alternative splicing results in multiple transcript variants.
Gene ID 5431
Gene name POLR2B
Swiss P30876
Synonym POLR2B,POL2RB,RPB2,hRPB140,POLR2B Rabbit pAb,3'-5' exoribonuclease,DNA-directed RNA polymerase II 140 kDa polypeptide,DNA-directed RNA polymerase II subunit B,RNA polymerase II subunit 2,RNA polymerase II subunit B2,RNA-directed RNA polymerase II subunit RPB2
Functions DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Second largest component of RNA polymerase II which synthesizes mRNA precursors and many functional non-coding RNAs. Proposed to contribute to the polymerase catalytic activity and forms the polymerase active center together with the largest subunit. 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. RPB2 is part of the core element with the central large cleft, the clamp element that moves to open and close the cleft and the jaws that are thought to grab the incoming DNA template (By similarity).
