    Summary
    Predicted to enable DNA binding activity; DNA-directed 5'-3' RNA polymerase activity; and zinc ion binding activity. Predicted to contribute to RNA polymerase I activity; RNA polymerase II activity; and RNA polymerase III activity. Acts upstream of or within transcription by RNA polymerase II. Predicted to be located in nucleus. Predicted to be part of RNA polymerase I complex; RNA polymerase II, core complex; and RNA polymerase III complex. Is expressed in several structures, including cerebral cortex; nose; submandibular gland primordium; thymus primordium; and tooth. Orthologous to human POLR2K (RNA polymerase II, I and III subunit K). [provided by Alliance of Genome Resources, Dec 2024]

    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.
