Sup35 fibers

Sup35 Prions


Life demands that proteins fold into elaborate structures to perform the overwhelming majority of biological functions. We investigate how components of the proteostasis network enable cells to achieve successful protein folding. In particular, we seek to understand how cells prevent, reverse, or even promote the formation of diverse misfolded conformers, encompassing: prions, amyloids, fibrillar structures, amorphous aggregates and toxic soluble oligomers.
