Sirtuin-mediated deacetylation pathway stabilizes Werner syndrome protein.

abstract：:Ribosome display is a powerful tool for selecting and evolving protein functions through ligand-binding. Here, this in vitro system was used to perform selection based on the folding properties of proteins, independent of specific ligand-binding. The selection is based on two properties of misfolded proteins: (1) incr...
