    Summary
    Enables chromatin binding activity. Predicted to be involved in innate immune response; positive regulation of interferon-beta production; and tRNA transcription by RNA polymerase III. Predicted to be located in cytoplasm and nucleoplasm. Predicted to be part of RNA polymerase III complex. Human ortholog(s) of this gene implicated in Wiedemann-Rautenstrauch syndrome and hypomyelinating leukodystrophy 7. Orthologous to human POLR3A (RNA polymerase III 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.
