Protein-based inheritance in Saccharomyces cerevisiae: [URE3] as a prion form of the nitrogen regulatory protein Ure2.

abstract：:General and regulated proteolysis in bacteria is crucial for cellular homeostasis and relies on high substrate specificity of the executing AAA+ proteases. Here we summarize the various strategies that tightly control substrate degradation from both sides: the generation of accessible degrons and their specific recogn...
