Transcriptional and post-transcriptional regulation of autophagy in the yeast Saccharomyces cerevisiae [Cell Biology]

January 25th, 2018 by Elizabeth Delorme-Axford, Daniel J. Klionsky

Autophagy is a highly conserved catabolic pathway that is vital for development, cell survival and the degradation of dysfunctional organelles and toxic aggregates. Dysregulation of autophagy is associated with cancer, neurodegeneration and lysosomal storage diseases. Accordingly, autophagy is precisely regulated at multiple levels (transcriptional, post-transcriptional, epigenetic, translational and post-translational) to prevent aberrant activity. Various model organisms exist to study autophagy but the baker's yeast Saccharomyces cerevisiae continues to be very advantageous for genetic and biochemical analysis of non-selective and selective autophagy. In this review, we focus on the cellular mechanisms that regulate autophagy transcriptionally and post-transcriptionally in S. cerevisiae.
