We compared the stability of intermediate and mature forms of Oct1 substrate proteins in organello and in vivo and found that Oct1 cleavage increases the half-life of its substrate proteins, most likely by removing destabilizing amino acids at the intermediate’s N-terminus. Thus Oct1 converts unstable precursor intermediates generated by MPP into stable mature proteins.
