Summary
Protein aggregation may occur due to the absence of natural chaperone partners. Targeting these partners offers a novel strategy for developing anti-aggregation therapies for protein misfolding diseases.
Area of Science:
- Biochemistry
- Molecular Biology
- Structural Biology
Background:
- Protein aggregation is a known phenomenon studied for decades.
- Existing principles of protein aggregation are well understood.
- Functional protein surfaces are implicated in aggregation.
Purpose of the Study:
- To propose a novel perspective on protein aggregation.
- To hypothesize that aggregation is a side-effect of lacking natural chaperone partners.
- To suggest a new therapeutic strategy for protein aggregation diseases.
Main Methods:
- Review of existing literature on protein aggregation.
- Analysis of paradigmatic examples supporting the hypothesis.
- Theoretical substantiation of the proposed mechanism.
Main Results:
- Protein aggregation may result from the absence of physiological chaperone partners.
- Functional protein surfaces, when unbound, can promote aggregation.
- Three examples support the generality of this hypothesis.
Conclusions:
- The lack of natural partners acting as chaperones can drive protein aggregation.
- Targeting these physiological partners is a direct approach for anti-aggregation molecule design.
- This perspective offers a new strategy for combating protein aggregation and misfolding diseases.

Protein-protein Interfaces
14.1K
Many proteins form complexes to carry out their functions, making protein-protein interactions (PPIs) essential for an organism's survival. Most PPIs are stabilized by numerous weak noncovalent chemical forces. The physical shape of the interfaces determines the way two proteins interact. Many globular proteins have closely-matching shapes on their surfaces, which form a large number of weak bonds. Additionally, many PPIs occur between two helices or between a surface cleft and a...

Protein Folding
10.0K
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.

Protein Networks
4.3K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Amyloid Fibrils
11.0K
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,...

Globular Proteins
9.3K
In organisms, proteins are the most abundant macromolecules. They act as the building blocks of life and play various crucial roles in the body. Proteins can be broadly classified into two distinct subtypes based on their shape and solubilities: globular proteins and fibrous proteins.
Globular proteins serve many important physiological functions, such as acting as enzymes, cellular messengers, and molecular transporters. These roles often require the proteins to be soluble in the aqueous...
