    Summary
    Enables RS domain binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Located in nuclear speck. Is expressed in several structures, including central nervous system; genitourinary system; peripheral nervous system; sensory organ; and skeleton. Orthologous to human U2AF1 (U2 small nuclear RNA auxiliary factor 1). [provided by Alliance of Genome Resources, Dec 2024]

    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.
