Strong Growth Polarity of Yeast Prion Fiber Revealed by Single Fiber Imaging

1 Sept 2001

Abstract excerpt

Using the yeast prion as a model, we have developed a novel system to observe the growth of individual prion fibers directly. NM fragments, the prion-determining region of the yeast protein Sup35p, were labeled by either red or green fluorescent dyes, and the fiber growth was observed under a fluorescence microscope. When green-Sup35NM was added to the preformed fibers made of red-Sup35NM, 70-97% of green fibers...
