FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] 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.

PHENOTYPE: Homozygotes for a reporter allele show prenatal lethality. Homozygotes for a small deletion in the C-terminal domain are viable, fertile and developmentally normal. Homozygotes for a larger deletion show reduced fetal size and partial postnatal lethality; survivors are small but otherwise normal. [provided by MGI curators]
