Figure 1 Sensing Mitochondrial (Dys)function at the Protein Import Machinery (A) In healthy mitochondria, ATFS-1 is imported via the presequence pathway after rapid degradation by the matrix protease Lon. Δψ, membrane potential; MPP, mitochondrial presequence peptidase. (B) In stressed mitochondria, ATFS-1 import is inhibited, thereby favoring nuclear translocation where it activates transcription of stress response genes. P, phosphorylation.
