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, Apr 2022]
