Study Notes
Post-Translational Modifications
- Post-translational modifications of peptide chain occur in the cytoplasm.
Prion Characteristics
- Primary characteristic of prions: infectious proteins that can cause normal proteins to fold abnormally.
Prion Consequences
- Presence of abnormal prion particles or beta-plated prion particles leads to neurodegenerative diseases.
Prion Conversion
- Prions convert normal proteins into abnormal, infectious prion proteins.
Prion Protein Resistance
- Pathological prion proteins are resistant to proteolytic degradation and heat denaturation.

Description
Test your knowledge about prions, their unique characteristics, and their role in causing prion-related diseases. Learn about how prions can corrupt naturally produced proteins, leading to the accumulation of pathological beta-plated particles and the development of amyloidosis.
