Prions and prion-like proteins.
Prions are self-replicating protein aggregates and are the primary causative factor in a number of neurological diseases in mammals. The prion protein (PrP) undergoes a conformational transformation leading to aggregation into an infectious cellular pathogen. Prion-like protein spreading and transmission of aggregates between cells have also been demonstrated for other proteins associated with ...
متن کاملClassifying prion and prion-like phenomena
The universe of prion and prion-like phenomena has expanded significantly in the past several years. Here, we overview the challenges in classifying this data informatically, given that terms such as "prion-like", "prion-related" or "prion-forming" do not have a stable meaning in the scientific literature. We examine the spectrum of proteins that have been described in the literature as forming...
متن کاملPrion and Prion-like Diseases in Humans
Introduction. Genetic prion diseases, such as Creutzfeldt-Jakob disease (CJD), Gerstmann-Straussler-Scheinker disease (GSS), Fatal Familial Insomnia (FFI), are associated with the mutations of prion (PRNP) gene. More than 30 pathogenic PRNP mutations were identified. Since Alzheimer disease (AD) and prion diseases have many similarities in the neuropathological and physiological symptoms, we te...
متن کاملRecent progress in prion and prion-like protein aggregation.
Prion diseases and prion-like protein misfolding diseases involve the accumulation of abnormally aggregated forms of the normal host proteins, such as prion protein and Tau protein. These proteins are special because of their self-duplicating and transmissible characteristics. Such abnormally aggregated proteins mainly formed in neurons, cause the neurons dysfunction, and finally lead to invari...
متن کاملPrion Proteins and Sleep Disturbances
Prions normally exist as cellular membrane proteins. In humans, 209 amino acids with one disulfide bond form a primarily alpha-helical prion protein structure with a molecular mass of 35 to 36 kDa. The specific role and function of the prion protein elude research efforts and remains a controversial topic. Misfolding of the native prion protein leads to a protein structure with increased propor...
