Predicted to enable catalytic activity and metal ion binding activity. Predicted to contribute to tRNA-specific adenosine-34 deaminase activity. Predicted to act upstream of or within tRNA processing. Predicted to be active in cytoplasm and nucleus. Human ortholog(s) of this gene implicated in neurodevelopmental disorder with brain abnormalities, poor growth, and dysmorphic facies. Orthologous to human ADAT3 (adenosine deaminase tRNA specific 3).
