Predicted to enable metalloendopeptidase activity. Predicted to contribute to metallopeptidase activity. Predicted to be involved in protein processing involved in protein targeting to mitochondrion. Located in mitochondrial inner membrane. Is expressed in several structures, including extraembryonic component; gallbladder; genitourinary system; gut gland; and nervous system. Human ortholog(s) of this gene implicated in multiple mitochondrial dysfunctions syndrome 6. Orthologous to human PMPCB (peptidase, mitochondrial processing subunit beta).
