Focus on Chaperones and Chaperonins
The 2011 Albert Lasker Basic Medical Research Award honors F. Ulrich Hartl and Arthur L. Horwich, for their "discoveries concerning the cell's protein-folding machinery, exemplified by cage-like structures that convert newly made proteins into their biologically active forms." We celebrate the award by presenting a collection of recent papers on chaperones and chaperonins published in NSMB. We also call your attention to our 2009 Focus on Protein Folding.
