Recombinant Human Polymerase II Polypeptide E
Sterile Filtered colorless solution.
Introduction: DNA-directed RNA polymerases I, II, and III subunit RPABC1 (POLR2E) is a member of the archaeal RpoH/eukaryotic RPB5 RNA polymerase subunit family. POLR2E being a DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the 4 ribonucleoside triphosphates as substrates. POLR2E is the 5th largest subunit of RNA polymerase II (the polymerase which is responsible for synthesizing messenger RNA in eukaryotes). The POLR2E subunit is shared by the other 2 DNA-directed RNA polymerases and is present in two-fold molar excess over the other polymerase subunits. An interaction between the POLR2E subunit and a hepatitis virus transactivating protein has been established, suggesting that an interaction between transcriptional activators and the polymerase can occur through the POLR2E subunit.
NCBI and Uniprot Product Information
NCBI Description
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, Jul 2008]
Uniprot Description
POLR2E: DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the four ribonucleoside triphosphates as substrates. Common component of RNA polymerases I, II and III which synthesize ribosomal RNA precursors, mRNA precursors and many functional non-coding RNAs, and small RNAs, such as 5S rRNA and tRNAs, respectively. Pol II is the central component of the basal RNA polymerase II transcription machinery. Pols are composed of mobile elements that move relative to each other. In Pol II, POLR2E/RPB5 is part of the lower jaw surrounding the central large cleft and thought to grab the incoming DNA template. Seems to be the major component in this process. Belongs to the archaeal RpoH/eukaryotic RPB5 RNA polymerase subunit family.
