Predicted to enable RNA binding activity; enzyme binding activity; and nucleotidyltransferase activity. Predicted to be involved in U6 snRNA 3'-end processing; mRNA polyadenylation; and pre-mRNA cleavage required for polyadenylation. Predicted to be located in cytosol; nucleolus; and nucleoplasm. Predicted to be active in nuclear speck. Orthologous to human TUT1 (terminal uridylyl transferase 1, U6 snRNA-specific). [provided by Alliance of Genome Resources, Apr 2022]
