Barth H, et al. (2002) Mai1p is essential for maturation of proaminopeptidase I but not for autophagy. FEBS Lett 512(1-3):173-9
Abstract: We here identify Mai1p, a homologue of the autophagy protein Aut10p, as a novel component essential for proaminopeptidase I (proAPI) maturation under non-starvation conditions. In mai1Delta cells mature vacuolar proteinases are detectable and vacuolar acidification is normal. In mai1Delta cells autophagy occurs, though at a somewhat reduced level. This is indicated by proAPI maturation during starvation and accumulation of autophagic bodies during starvation with phenylmethylsulfonyl fluoride. Homozygous diploid mai1Delta cells sporulate, but with a slightly reduced frequency. Biologically active Ha-tagged Mai1p, chromosomally expressed under its native promoter, is at least in part peripherally membrane-associated. In indirect immunofluorescence it localizes to the vacuolar membrane or structures nearby. In some cells Ha-tagged Mai1p appears concentrated at regions adjacent to the nucleus.
