SMASh: a drug-inducible protein turnover control system

SMASh

SMASh (Small-Molecule-Assisted Shutoff) degron system was developed and optimized to allow targeted and time-controlled degradation of a protein of interest. It was built as a self-cleaving degron that can be stabilized upon drug treatment (Chung HK et al. Nat Chem Biol 2015).

This drug-inducible and reversible protein degradation system is of particular interest to model-targeted protein degradation therapeutic approaches in preclinical stages (learn more: Targeted Protein Degradation: New Promises for "Undruggable" Diseases). It can also be used to create targeted inducible and reversible knock-out and knock-down systems.

SMASh does not need to be coupled to any other reagent to function; a single genetic modification allows for the development of an inducible and reversible targeted protein degradation system.

Access to a new innovative technology for targeted time-controlled protein degradation

The SMASh degron system was developed and first described in 2015 (Chung HK et al. Nat Chem Biol 2015 and US62/186,339). It has been shown to be functional in yeast, virus, and mammalian cells, and has been used in drug discovery (Rago et al. Biochem Biophys Res Commun 2019).
