    Summary
    Predicted to enable U2 snRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome and spermatogenesis. Predicted to be located in nuclear speck. Predicted to be part of U2 snRNP; U2-type catalytic step 2 spliceosome; and U2-type precatalytic spliceosome. Human ortholog(s) of this gene implicated in connective tissue disease. Orthologous to human SNRPA1 (small nuclear ribonucleoprotein polypeptide A'). [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.
