Rpb1 (phospho Ser1619) Polyclonal Antibody

Rabbit Anti-Rpb1 (phospho Ser1619) Polyclonal Antibody

Product Specifications

Background

POLR2A (RNA polymerase II subunit A) encodes the largest subunit of RNA polymerase II, the polymerase responsible for synthesizing messenger RNA in eukaryotes. The product of POLR2A 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.
