Rpb1 (phospho Ser1619) rabbit pAb from ELK Biotechnology Read more ›
Rpb1 (phospho Ser1619) rabbit pAb is a research-use antibody from ELK Biotechnology for studying Rpb1 in WB, IHC, IF, ELISA workflows with listed reactivity for Human, Mouse, Rat, Monkey. Specifications and supporting documents below should be reviewed when planning the experiment.
This gene encodes the largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of this gene contains a carboxy terminal domain composed of heptapeptide repeats that are essential for polymerase activity. These repeats contain serine and threonine residues that are phosphorylated in actively transcribing RNA polymerase. In addition, this subunit, in combination with several other polymerase subunits, forms the DNA binding domain of the polymerase, a groove in which the DNA template is transcribed into RNA.
