Predicted to enable 3'-tRNA processing endoribonuclease activity and tRNA-specific ribonuclease activity. Predicted to be involved in mitochondrial tRNA 3'-trailer cleavage, endonucleolytic. Predicted to be located in mitochondrial nucleoid and nucleoplasm. Predicted to be active in mitochondrion. Human ortholog(s) of this gene implicated in combined oxidative phosphorylation deficiency 17. Orthologous to human ELAC2 (elaC ribonuclease Z 2). [provided by Alliance of Genome Resources, Apr 2022]
