Important Information
Prions and Prion-like Proteins
Prions and prion-like proteins are defined as proteins (human or animal) that fall into one of the below categories:
- Proteins that are highly associated with proteinpathies, including, but not limited to:
- Major prion protein/PrP/CD230 (Creutzfeldt-Jakob Disease [CJD], variant Creutzfeldt-Jakob Disease [vCJD], Kuru, fatal familial insomnia, bovine spongiform encephalopathy, Gerstmann Straussler-Scheinker syndrome)
- Alpha-synuclein (Parkinson’s disease)
- Tau, beta-amyloid (Alzheimer’s disease)
- Tau, RNA-binding protening Fused in Sarcome (FUS) (Frontotemporal lobar dementias)
- Polyglutamine-containing proteins (polyQ) (Huntington’s disease)
- Superoxide dismutase 1 (SOD1); transactivations response element (TAR) DNA-binding protein-43 (TDP- 43); RNA-binding proteing Fused in Sarcoma (FUS); Ubiquilin (ALS/Lou Gehrig’s disease)
- Proteins that confer a disease state that is transmissible from cell to cell.
- Proteins that have a fibrillar or aggregated form that has been shown to “seed” a pathology associated with a disease.
