Predicted to enable metal ion binding activity and metalloendopeptidase activity. Predicted to be involved in mitochondrial protein processing and mitochondrial proton-transporting ATP synthase complex assembly. Predicted to act upstream of or within proteolysis. Predicted to be located in several cellular components, including cell junction; cytosol; and plasma membrane. Predicted to be extrinsic component of mitochondrial inner membrane. Orthologous to human ATP23 (ATP23 metallopeptidase and ATP synthase assembly factor homolog). [provided by Alliance of Genome Resources, Apr 2022]
