Automated description from the Alliance of Genome Resources (Release 5.0.0)
Enables 5'-3' exoribonuclease activity; RNA binding activity; and endoribonuclease activity. Involved in RNA phosphodiester bond hydrolysis, exonucleolytic and mRNA 3'-end processing by stem-loop binding activity and cleavage. Part of mRNA cleavage and polyadenylation specificity factor complex. Orthologous to human CPSF3 (cleavage and polyadenylation specific factor 3).
