What is viral protein?

Protein (PrP) is a highly conserved glycoprotein. Normal dirty virus is widely expressed on the surface of vertebrate cells, which may be related to the maintenance of nervous system function, lymphocyte signal transduction and nucleic acid metabolism. Pathogenic prions (Pr~) are conformational isomers of PrP, and there is no * * * valence bond difference between them. PrP~+can cause a series of fatal neurodegenerative diseases, which are related to the protein conformation of prions. [ 1]

The discovery of prion broke the traditional idea that "virus must have nucleic acid", so it is of great significance in theory. (Pr)prpst (-m) Human prion diseases include: Kuru disease, Gerstmdann syndrome, GSS), Creutzfeldt-Jakob disease (JD), new variant CJD or human mad cow disease and fatal familial insomnia. Prion diseases of animals include: bovine spongiform encephalopathy, commonly known as mad cow disease; Sheep itch; Mink infectious encephalopathy and cat spongiform encephalopathy. The typical symptoms of this kind of diseases are dementia, loss of coordination and nervous system disorder, and the main lesion is amyloidosis in protein. Such diseases are hereditary, contagious and sporadic.
