Polr2i - polymerase (RNA) II (DNA directed) polypeptide I

Predicted to enable nucleic acid binding activity and zinc ion binding activity. Predicted to contribute to DNA-directed 5'-3' RNA polymerase activity. Predicted to be involved in maintenance of transcriptional fidelity during DNA-templated transcription elongation from RNA polymerase II promoter; transcription initiation from RNA polymerase II promoter; and transcription-coupled nucleotide-excision repair. Predicted to be located in nucleoplasm. Predicted to be part of RNA polymerase II, core complex. Is expressed in several structures, including alimentary system; blastocyst; integumental system; nervous system; and urinary system. Orthologous to human POLR2I (RNA polymerase II subunit I).
