Summary: 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 transcription elongation by RNA polymerase II; transcription initiation at 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).

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
