Predicted to enable RNA binding activity. Predicted to be involved in mRNA 3'-end processing by stem-loop binding activity and cleavage; mRNA polyadenylation; and pre-mRNA cleavage required for polyadenylation. Predicted to be part of mRNA cleavage and polyadenylation specificity factor complex. Orthologous to human CPSF2 (cleavage and polyadenylation specific factor 2).
