    Summary
    Enables chromatin binding activity. Acts upstream of or within anterior/posterior pattern specification; blastocyst formation; and mRNA splicing, via spliceosome. Located in chromatin and nuclear matrix. Part of U2 snRNP. Is expressed in several structures, including central nervous system; endocrine gland; genitourinary system; hemolymphoid system gland; and sensory organ. 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.
