Proteostasis integrates biological pathways controlling biogenesis, trafficking, folding, and degradation of proteins. This book focuses on two protein breakdown/degradation processes (proteolysis), which are part of a normally functioning proteostatic system: the ubiquitin-proteasome system and autophagy.
