    Summary
    Predicted to enable U1 snRNA binding activity and snRNP binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in cytoplasmic ribonucleoprotein granule; fibrillar center; and nuclear speck. Predicted to be part of nucleus. Is expressed in 8-cell stage embryo; brain; submandibular gland primordium; and vibrissa. Human ortholog(s) of this gene implicated in connective tissue disease. Orthologous to human SNRPB2 (small nuclear ribonucleoprotein polypeptide B2). [provided by Alliance of Genome Resources, Apr 2022]

    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.
