Required for the assembly of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I) (, ). Involved in mid-late stages of complex I assembly .
Subcellular locations: Mitochondrion inner membrane
According to a report, it is associated with the matrix face of the mitochondrial inner membrane and does not contain any transmembrane region. However, one transmembrane domain is clearly predicted by different methods (Probable).
