    Summary
    Predicted to enable RNA polymerase I core promoter sequence-specific DNA binding activity. Predicted to be involved in RNA polymerase I preinitiation complex assembly and nucleolar large rRNA transcription by RNA polymerase I. Predicted to act upstream of or within transcription by RNA polymerase I. Predicted to be located in nucleolus and nucleoplasm. Predicted to be part of RNA polymerase I core factor complex and RNA polymerase transcription factor SL1 complex. Is expressed in heart and limb. Human ortholog(s) of this gene implicated in Lynch syndrome and mismatch repair cancer syndrome. Orthologous to human TAF1B (TATA-box binding protein associated factor, RNA polymerase I subunit B).

    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.

      Status: VALIDATED

      Description
      Transcript Variant: This variant (2) lacks an exon, compared to variant 1. This variant is represented as non-coding because the use of the 5'-most supported translational start codon, as used in variant 1, renders the transcript a candidate for nonsense-mediated mRNA decay (NMD).
