Abstract:
Sup35 in its native state is a translation termination factor in Saccharomyces cerevisiae. The prion domain of Sup35p can form amyloid-like proteinaceous fibrils in vitro and in vivo. Furthermore, the in-register cross beta-sheet structure of Sup35p amyloid fibrils is similar to those formed in other species. Therefore, studies on mechanism of Sup35p self-assembly can be an appropriate model to study protein misfolding-related diseases and prion biology. Because of its ability to self-assemble into nanowires, the prion domain of Sup35p has been widely used in biotechnology and nanotechnology.
