An Analysis of Prion Protein PRNP, P04156, Human




By: Lorenzo Angelus Fernandez

5/5/2023




CHEM 4300

California State University Los Angeles

Professor: Dr Anthony Lee

, Introduction:



Prions (PrP) are abnormal, misfolded protein pathogens known to cause neurodegenerative

diseases such as Variant Creutzfeldt-Jakob Disease (vCJD) and formerly Kuru in humans,

Scrapie in sheep, Bovine Spongiform Encephalopathy (BSE) in cattle, and chronic wasting

disease (CWD) in cervids like deer and moose. Prion diseases are incredibly contagious and

completely fatal. Means of infection include exposure to PrP contaminated food, medical

equipment, and exposure to body fluids of infected animals such as blood and urine. Prion

diseases are protein misfolding diseases that interfere with normal function, resulting in cell

death and infection. Because prions are not viruses, bacteria or other organismal

pathogens, typical means of repelling infections are generally ineffective. Prions cannot be

killed, as they are misfolded proteins rather than full cells.
