Abstract:The Rnq1 protein is one of the best-studied yeast prions. It has a large potentially prionogenic C-terminal region of about 250 residues. However, a previous study indicated that only 40 C-terminal residues form a prion structure. Here, we mapped the actual and potential prion structures formed by Rnq1 and its variants truncated from the C-terminus in two [RNQ+] strains using partial proteinase K digestion. The location of these structures differed in most cases from previous predictions by several computer al… Show more
