Predicted to contribute to RNA binding activity. Predicted to be involved in mRNA polyadenylation and pre-mRNA cleavage required for polyadenylation. Predicted to act upstream of or within mRNA processing. Located in nucleus. Part of mRNA cleavage and polyadenylation specificity factor complex. Orthologous to human FIP1L1 (factor interacting with PAPOLA and CPSF1). [provided by Alliance of Genome Resources, Apr 2022]
