Pexophagy: The Selective Degradation of Peroxisomes

Figure 5

Signal transduction cascades regulating selective autophagy in yeast. Mitogen-activated protein kinase (MAPK) cascades contribute to differential regulation of selective autophagy pathways. As recently shown, the Slt2 and Hog1 signal transduction pathways regulate both mitophagy and pexophagy [37, 96]. Besides the obvious role of environmental factors such as nutritional conditions, details of other upstream events are poorly understood.
