Anti-RPB5/POLR2E Antibody Picoband®
Primary Antibody supplied by Boster Bio Read more ›

Product Description
DNA-ed RNA polymerases I, II, and III subunit RPABC1 is a protein that in humans is encoded by the POLR2E gene. This gene encodes the fifth largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. This subunit is shared by the other two DNA-ed RNA polymerases and is present in two-fold molar excess over the other polymerase subunits. An interaction between this subunit and a hepatitis virus transactivating protein has been demonstrated, suggesting that interaction between transcriptional activators and the polymerase can occur through this subunit. A pseudogene is located on chromosome 11. Three transcript variants encoding two different isoforms have been found for this gene.
