Predicted to enable ATP binding activity and RNA helicase activity. Predicted to be involved in RNA catabolic process; cellular response to DNA damage stimulus; and maturation of 5.8S rRNA. Predicted to act upstream of or within RNA splicing and mRNA processing. Predicted to be located in nucleoplasm. Predicted to be part of TRAMP complex; catalytic step 2 spliceosome; and nuclear exosome (RNase complex). Predicted to be active in nucleus. Orthologous to human MTREX (Mtr4 exosome RNA helicase).
