DNA Origami as Scaffolds for Self‐Assembly of Lipids and Proteins

Since first being reported in 2006, the DNA origami approach has attracted increasing attention due to programmable shapes, structural stability, biocompatibility, and fantastic addressability. Herein, we provide an account of recent developments of DNA origami as scaffolds for templating the selfassembly of distinct biocomponents, essentially proteins and lipids, into a diverse spectrum of integrated supramolecular architectures. First, the historical development of the DNA origami concept is briefly reviewed. Next, various applications of DNA origami constructs in controllable directed assembly of soluble proteins are discussed. The manipulation and self-assembly of lipid membranes and membrane proteins by using DNA origami as scaffolds are also addressed. Furthermore, recent progress in applying DNA origami in cryoelectron microscopy analysis is discussed. These advances collectively emphasize that the DNA origami approach is a highly versatile, fast evolving tool that may be integrated with lipids and proteins in a way that meets future challenges in molecular biology and nanomedicine.
