    Summary
    Predicted to enable RNA polymerase III general transcription initiation factor activity and RNA polymerase III type 3 promoter sequence-specific DNA binding activity. Acts upstream of or within regulation of mRNA stability. Predicted to be part of transcription factor TFIIIB complex and transcription preinitiation complex. Predicted to be active in nucleus. Human ortholog(s) of this gene implicated in cerebellofaciodental syndrome. Orthologous to human BRF1 (BRF1 RNA polymerase III transcription initiation factor subunit).

    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.
