Description
POLR2I Human Recombinant produced in E.Coli is a single, non-glycosylated polypeptide chain containing 148 amino acids (1-125 a.a.) and having a molecular mass of 17.0kDa. POLR2I is fused to a 23 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques.
Introduction
Polymerase II Polypeptide I (POLR2I) is a member of the archaeal RpoM/eukaryotic RPA12/RPB9/RPC11 RNA polymerase family. POLR2I is a subunit of RNA polymerase II, which is a polymerase responsible for synthesizing messenger RNA in eukaryotes. DNA-dependent RNA polymerase catalyzes the transcription of DNA into RNA using the 4 ribonucleoside triphosphates as substrates. In addition POLR2I synthesizes mRNA precursors and numerous functional non-coding RNAs.
