Predicted to enable guanylyltransferase activity and polynucleotide adenylyltransferase activity. Predicted to be involved in RNA 3' uridylation; regulation of mRNA stability; and response to xenobiotic stimulus. Predicted to act upstream of or within mRNA processing. Predicted to be located in Golgi apparatus; nuclear membrane; and nucleoplasm. Predicted to be part of TRAMP complex. Predicted to be active in nucleolus. Is expressed in several structures, including alimentary system; brain; genitourinary system; hemolymphoid system gland; and musculoskeletal system. Orthologous to human TENT4A (terminal nucleotidyltransferase 4A). [provided by Alliance of Genome Resources, Apr 2022]
