Enables C2H2 zinc finger domain binding activity. Involved in RNA splicing. Predicted to be located in nucleus. Predicted to be part of Prp19 complex; U2-type spliceosomal complex; and U2AF complex. Predicted to be active in nuclear speck. Is expressed in several structures, including alimentary system; central nervous system; liver lobe; lower urinary tract; and nose. Orthologous to human U2AF2 (U2 small nuclear RNA auxiliary factor 2). [provided by Alliance of Genome Resources, Apr 2022]
