The ...The coronavirus (CoV) spike (S) protein, involved in viral-host cell fusion, is the primary immunogenic target for virus neutralization and the current focus of many vaccine design efforts. The highly flexible S-protein, with its mobile domains, presents a moving target to the immune system. Here, to better understand S-protein mobility, we implemented a structure-based vector analysis of available β-CoV S-protein structures. Despite an overall similarity in domain organization, we found that S-proteins from different β-CoVs display distinct configurations. Based on this analysis, we developed two soluble ectodomain constructs for the SARS-CoV-2 S-protein, in which the highly immunogenic and mobile receptor binding domain (RBD) is either locked in the all-RBDs 'down' position or adopts 'up' state conformations more readily than the wild-type S-protein. These results demonstrate that the conformation of the S-protein can be controlled via rational design and can provide a framework for the development of engineered CoV S-proteins for vaccine applications. #1: Journal: bioRxiv / Year: 2020 Title: Controlling the SARS-CoV-2 Spike Glycoprotein Conformation.

The highly flexible S-protein, with its mobile domains, presents a moving target to the immune system. Here, to better understand S-protein mobility, we implemented a structure-based vector analysis of available β-CoV S-protein structures. We found that despite overall similarity in domain organization, different β-CoV strains display distinct S-protein configurations. Based on this analysis, we developed two soluble ectodomain constructs in which the highly immunogenic and mobile receptor binding domain (RBD) is locked in either the all-RBDs 'down' position or is induced to display a previously unobserved in SARS-CoV-2 2-RBDs 'up' configuration. These results demonstrate that the conformation of the S-protein can be controlled via rational design and provide a framework for the development of engineered coronavirus spike proteins for vaccine applications. | ||||||||||||||||||
