Automated description from the Alliance of Genome Resources (Release 7.0.0)
Enables several functions, including 5'-3' exonuclease activity; hydrolase activity, acting on acid anhydrides, in phosphorus-containing anhydrides; and magnesium ion binding activity. Involved in NAD-cap decapping; RNA destabilization; and nuclear mRNA surveillance. Predicted to be located in nucleoplasm and plasma membrane. Predicted to be active in cytosol and nucleus. Orthologous to human DXO (decapping exoribonuclease).
