    Summary
    Predicted to enable several functions, including DNA-directed 5'-3' RNA polymerase activity; DNA/RNA hybrid binding activity; and metal ion binding activity. Predicted to contribute to RNA polymerase I activity. Predicted to be involved in negative regulation of protein localization to nucleolus and rRNA transcription. Located in chromosome and nucleus. Part of RNA polymerase I complex. Is expressed in several structures, including alimentary system; brain; early conceptus; genitourinary system; and integumental system. Human ortholog(s) of this gene implicated in acrofacial dysostosis Cincinnati type and hypomyelinating leukodystrophy. Orthologous to human POLR1A (RNA polymerase I subunit A).

    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.
