Predicted to enable U2 snRNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome and spermatogenesis. Predicted to act upstream of or within RNA splicing and mRNA processing. Part of U2 snRNP. Is expressed in several structures, including hemolymphoid system; liver; metanephros; nervous system; and sensory organ. Human ortholog(s) of this gene implicated in connective tissue disease. Orthologous to human SNRPA1 (small nuclear ribonucleoprotein polypeptide A').
