ABSTRACT
Protein homeostasis is epitomized by an equilibrium between protein biosynthesis and degradation the 'life and death' of proteins. Approximately one-third of newly synthesized proteins are degraded. As such, protein turnover is required to maintain cellular integrity and survival. Autophagy and the ubiquitin-proteasome system (UPS) are the two principal degradation pathways in eukaryotes. Both pathways orchestrate many cellular processes during development and upon environmental stimuli. Ubiquitination of degradation targets is used as a 'death' signal by both processes. Recent findings revealed a direct functional link between both pathways. Here, we summarize key findings in the field of protein homeostasis, with an emphasis on the newly revealed crosstalk between both degradation machineries and how it is decided which pathway facilitates target degradation.
