Abstract
During human adenovirus type 3 (Ad3) infection, an excess of penton base and fiber proteins are produced. These form dodecahedral particles composed of 12 pentamers of penton base and 12 trimers of fiber protein. Beside this “natural” expression, the adenovirus dodecahedron can be expressed in the heterologous baculovirus system in two forms: a fiber-devoid dodecahedron made only of 12 penton bases (called base-dodecahedron: Bs-Dd) and the fiber-containing dodecahedron (called penton dodecahedron: Pt-Dd). These particles partly mimic the adenoviral cellular entry pathway but are devoid of genetic information making them an unusual tool for basic research or applications. We report here how these particles are expressed and purified, the labeling method for trafficking studies as well as their use in molecular interaction studies. The potential of these particles for biotechnological applications is under evaluation, making their study a “niche” along side traditional adenoviral vectors.
