In vitro assembly of retroviruses
WebMay 28, 2024 · In vitro assembly of Gag and CA protein into immature virus-like particles (VLPs) and mature capsid-like particles (CLPs) has facilitated study of the lattice structure of many retroviruses 16. WebA biomimetic minimalist model membrane was used to study the mechanism and kinetics of cell-free in vitro HIV-1 Gag budding from a giant unilamellar vesicle (GUV). Real-time interaction of Gag, RNA, and lipid, leading to the formation of mini-vesicles, was measured using confocal microscopy. Gag forms resolution-limited punctae on the GUV lipid ...
