Predicted to enable bisphosphoglycerate 3-phosphatase activity; inositol-hexakisphosphate phosphatase activity; and tRNA-specific adenosine deaminase activity. Predicted to contribute to tRNA-specific adenosine-34 deaminase activity. Predicted to act upstream of or within tRNA wobble adenosine to inosine editing. Predicted to be located in endoplasmic reticulum lumen; extracellular region; and plasma membrane. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in papillary thyroid carcinoma and pontocerebellar hypoplasia type 16. Orthologous to human MINPP1 (multiple inositol-polyphosphate phosphatase 1).
