The proteasome regulates timed degradation of proteins using both intrinsic and extrinsic receptors that recognize polyubiquitin chains on targets. In this issue of Structure, Chen et al. (2016) outline the structural basis of how intrinsic receptors prefer ubiquitin-like domains rather than ubiquitin, to bind extrinsic co-receptors.

The 26S proteasome degrades the majority of cellular proteins and affects all aspects of cellular life. Therefore, the 26S proteasome abundance, proper assembly, and activity in different life contexts need to be precisely controlled. Impaired proteasome activity is considered a causative factor in several serious disorders.

Proteolysis Targeting Chimeras (PROTACs) are bifunctional compounds that have been extensively studied for their role in targeted protein degradation (TPD). The capacity to degrade validated or undruggable targets provides PROTACs with significant potency in cancer therapy. However, the clinical application of PROTACs is limited by their poor potency and unfavorable pharmacokinetic properties.

Chronic limb-threatening ischemia (CLTI) is the most severe manifestation of peripheral arterial disease (PAD) and imposes a significantly high burden due to its high risk of mortality and amputation. Revascularization is the first-line treatment for CLTI; however, the amputation rate remains high, and approximately one-third of patients are not eligible for this treatment. Therefore, there is an urgent need for more effective therapeutic strategies.

Generating effective live vaccines from intact viruses remains challenging owing to considerations of safety and immunogenicity. Approaches that can be applied in a systematic manner are needed. Here we created a library of live attenuated influenza vaccines by using diverse cellular E3 ubiquitin ligases to generate proteolysis-targeting (PROTAR) influenza A viruses.
