The role of methionine oxidation in prion formation (360G-Wellcome-106507_Z_14_Z)

£150,896

How prions form spontaneously without underlying infection or genetic change is poorly understood at the molecular level, yet if we are to develop effective preventative measures for human and animal amyloidoses, this mechanism must be established. Of particular importance is identifying what can trigger this event. One strong possibility is that oxidative damage of the non-prion form of a protein may be an important trigger influencing the formation of its heritable prion conformation. This project will examine how an oxidized protein goes on to form a prion using the yeast [PSI+] and [PIN+] model prions. The specific goals of the project are: i) to test whether methionine sulphoxide reductases (MSRs) can protect against spontaneous prion formation using MSR mutants and oxidative stress conditions. ii) to determine whether methionine oxidation can occur on nascent ribosome-associated polypeptides during protein synthesis. iii) To examine whether antioxidants localise to ribosomes to protect nascent proteins against oxidation. Additionally to determine whether antioxidants localize to the sites of protein aggregation as part of the cellular antioxidant defences
