3.A.1.212.1
The mitochondrial peptide exporter, Mdl1p (exports peptides of 6-21 amino acyl residues from the mitochondrial matrix as well as degradation products of misassembled respiratory chain complexes) (Janas et al., 2003; van der Does et al., 2006; Gompf et al., 2007). A leaderless Mdl1p targets to the ER membrane instead of to the mitochondria (Gompf et al., 2007).
