To investigate the aggregation propensity into amyloid structures in avian PrPs, including chickens, mallards, geese and Pekin ducks, we investigated the aggregation propensity into amyloid structures in mammalian PrPs, including prion diseases susceptible animals (sheep and goats) and prion diseases resistant animal (dog) using AMYCO. The gene discussed is MSMB; the disease is prion disease.
