POLR2E Antibody (OTI3B5)

Western Blot: POLR2E Antibody (OTI3B5) [NBP2-00482] - POLR2A is destabilized by inhibition of oncogenic BRAFV600E signaling. Representative immunoblot of A375-P cells treated with PLX4720 or DMSO control for 16 hours, followed by cycoheximide treatment for the indicated timepoints. The lower panel shows the quantification of three independent biological replicates, normalized to the respective 0 CHX timepoint and alpha-Tubulin loading control (mean +/- SD).

Background

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-directed 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. [provided by RefSeq].
