    Summary
    Predicted to enable U2 snRNA binding activity. Involved in mRNA splicing, via spliceosome. Located in cytoplasm. Part of U2 snRNP and U2-type prespliceosome. Human ortholog(s) of this gene implicated in connective tissue disease. Orthologous to human SNRPA1 (small nuclear ribonucleoprotein polypeptide A').
