Predicted to enable several functions, including 5'-3' exonuclease activity; hydrolase activity, acting on acid anhydrides, in phosphorus-containing anhydrides; and magnesium ion binding activity. Predicted to be involved in RNA destabilization and nucleic acid metabolic process. Predicted to be located in nucleoplasm and plasma membrane. Predicted to be active in cytosol and nucleus. Orthologous to human DXO (decapping exoribonuclease). [provided by Alliance of Genome Resources, Apr 2022]
