    Summary
    Predicted to enable chromatin binding activity; mRNA binding activity; and splicing factor binding activity. Predicted to be involved in positive regulation of transcription by RNA polymerase III and spliceosomal complex assembly. Predicted to act upstream of or within anterior/posterior pattern specification; blastocyst formation; and mRNA splicing, via spliceosome. Predicted to be located in chromatin; nuclear matrix; and nuclear speck. Predicted to be part of nucleus. Human ortholog(s) of this gene implicated in hepatocellular carcinoma and myelodysplastic syndrome. Orthologous to human SF3B1 (splicing factor 3b subunit 1).

    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.
