Summary
Cells use molecular chaperones to maintain protein homeostasis, but misfolded proteins still cause diseases like cancer and neurodegeneration. Recent advances offer new hope for diagnosing and treating these protein-folding diseases.
Area of Science:
- Cellular Biology
- Biochemistry
- Molecular Medicine
Background:
- Cells possess sophisticated systems, including molecular chaperones, to ensure proper protein folding and maintain protein homeostasis.
- Errors in protein folding can lead to the accumulation of misfolded proteins, overwhelming cellular quality-control mechanisms like the proteasome and autophagy.
Discussion:
- Protein misfolding is implicated in numerous complex diseases, including neurodegenerative disorders and cancer, highlighting its significant clinical relevance.
- Understanding the intricate processes of protein folding is crucial for developing effective therapeutic strategies.
Key Insights:
- Molecular chaperones are essential for augmenting nascent polypeptide folding and mitigating cellular stress.
- Despite cellular quality-control mechanisms, protein misfolding remains a pathological hallmark of various diseases.
Outlook:
- Recent research using model systems has significantly advanced our understanding of protein folding.
- Continued investigation promises improved diagnostics and treatments for protein-folding diseases.

8.8K
Proteins are chains of amino acids linked together by peptide bonds. Upon synthesis, a protein folds into a three-dimensional conformation, critical to its biological function. Interactions between its constituent amino acids guide protein folding, and hence the protein structure is primarily dependent on its amino acid sequence.

Amyloid fibrils are aggregates of misfolded proteins. Under most circumstances, misfolded proteins are either refolded by chaperone proteins or degraded by the proteasome. However, in the case of a mutation or a disease, these proteins can accumulate to form large clusters and often further assemble to form elongated fibers, called fibrils.
Amyloid deposits were observed as early as 1639 in the liver and the spleen. In 1854, Rudolph Virchow performed iodine staining,...

14.7K
The native conformation of a protein is formed by interactions between the side chains of its constituent amino acids. When the amino acids cannot form these interactions, the protein cannot fold by itself and needs chaperones. Notably, chaperones do not relay any additional information required for the folding of polypeptides; the native conformation of a protein is determined solely by its amino acid sequence. Chaperones catalyze protein folding without being a part of the folded protein.
