Analysis of carboxy-terminal peptides derived from endoproteinase Lys-C digests of the scrapie isoform of the hamster prion protein revealed that the majority of the molecules are glycoinositol phospholipid linked through ethanolamine attached at serin-231. However, approximately 15% of PrPSc had a carboxy-terminal peptide that ends at glycine-228. It is intriguing that this glycine is part of the PrP sequence Gly-Arg-Arg, which is an established target sequence for the proteolysis and release of bioactive peptides from larger precursors. The mechanism of formation, as well as the role of the truncated carboxy terminus in the dissemination and neuropathology of scrapie, remains to be determined.

D011328 Prions Small proteinaceous infectious particles which resist inactivation by procedures that modify NUCLEIC ACIDS and contain an abnormal isoform of a cellular protein which is a major and necessary component. The abnormal (scrapie) isoform is PrPSc (PRPSC PROTEINS) and the cellular isoform PrPC (PRPC PROTEINS). The primary amino acid sequence of the two isoforms is identical. Human diseases caused by prions include CREUTZFELDT-JAKOB SYNDROME; GERSTMANN-STRAUSSLER SYNDROME; and INSOMNIA, FATAL FAMILIAL. Mink Encephalopathy Virus,Prion,Encephalopathy Virus, Mink
