Saccharomyces cerevisiae Hsp70 mutations affect [PSI+] prion propagation and cell growth differently and implicate Hsp40 and tetratricopeptide repeat cochaperones in impairment of [PSI+].

We previously described an Hsp70 mutant (Ssa1-21p), altered in a conserved residue (L483W), that dominantly impairs yeast [PSI(+)] prion propagation without affecting growth. We generated new SSA1 mutations that impaired [PSI(+)] propagation and second-site mutations in SSA1-21 that restored normal...
