Predicted to enable RNA binding activity. Predicted to be involved in mRNA splicing, via spliceosome. Predicted to be located in cytosol and nuclear speck. Predicted to be part of U2-type catalytic step 1 spliceosome; U2-type catalytic step 2 spliceosome; and U2-type precatalytic spliceosome. Orthologous to human CWC22 (CWC22 spliceosome associated protein homolog). [provided by Alliance of Genome Resources, Apr 2022]
