Besides the five genes we confirmed to be the suppressors of the autophagy defect of the arl1Δ or ypt6Δ strains, we also selected SLT2 and PEP3 for study. Slt2 is a MAP kinase that regulates the protein kinase C pathway (Madden et al. 1997) and mediates two selective forms of autophagy, mitophagy to clear the damaged mitochondria (Mao et al. 2011) and pexophagy for peroxisome clearance. Pep3 is a subunit of the CORVET (class C core vacuole/endosome tethering membrane) tethering complex and is required for the biogenesis of the vacuole (Preston et al. 1991; Srivastava et al. 2000). Although SLT2 and PEP3 did not suppress the autophagy defect of the arl1Δ or ypt6Δ strain, respectively, they did suppress the growth defect of the appropriate strain on rapamycin plates at 37°.
