| Post Translational Modification | PTM: Upon import into the mitochondrion, the N-terminal transit peptide is cleaved by the mitochondrial-processing peptidase (MPP) to generate an intermediate form which undergoes a second proteolytic cleavage mediated by proteases AFG3L1 and/or AFG3L2 removing an additional N-terminal fragment to generate the proteolytically active mature form. {ECO:0000250|UniProtKB:Q3ULF4}. |
