    Summary
    Predicted to enable poly-pyrimidine tract binding activity and pre-mRNA 3'-splice site binding activity. Predicted to be involved in spliceosomal complex assembly. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in nucleus. Predicted to be part of U2-type prespliceosome; U2AF complex; and commitment complex. Predicted to be active in nuclear speck. Human ortholog(s) of this gene implicated in developmental delay, dysmorphic facies, and brain anomalies. Orthologous to human U2AF2 (U2 small nuclear RNA auxiliary factor 2). [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.
