Amyloid Fibrils

Amyloid Fibrils

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, normally used to...

Protein Organization

Protein Organization

Proteins are polymers of amino acid residues. They are versatile and responsible for different cellular functions, including DNA replication, molecular transport, catalysis, and structural support. Proteins have a hierarchical structure comprising at least three levels of organization: primary, secondary, and tertiary structure. Some large proteins have a quaternary structure where individual protein subunits are linked together.
The primary structure of a protein is its amino acid sequence.

Protein Folding

Protein Folding

Protein Folding

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 Structure Is Critical to Its Biological Function
Proteins perform a wide range of biological functions such as catalyzing chemical reactions, providing...

Mechanical Protein Function

Mechanical Protein Function

Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.

Neuroscience
Biochemistry
Computational Biology

Background:

Prion diseases are rare neurodegenerative disorders.
Characterized by misfolding of the prion protein (PrP(C)) into a beta-strand rich 'scrapie form'.
This misfolding leads to disease pathogenesis.

Purpose of the Study:

To review computational approaches for understanding prion protein instability.
To explore how mutations, metal binding, and environmental factors influence PrP(C) fold.
To provide a structural basis for developing anti-prion therapeutics.

Main Methods:

Review of computational studies on prion protein structure and dynamics.
Analysis of factors affecting prion protein folding stability.
In silico modeling of anti-prion compound interactions.

Main Results:

Computational methods elucidate the intrinsic instability of the native prion protein fold.
Identified key factors (mutations, metal ions, pH, temperature) influencing PrP(C) stability.
Provided structural insights into the binding of potential anti-prion agents.

Conclusions:

Computational approaches are crucial for understanding prion protein misfolding.
These insights can guide the design of compounds to block prion conversion.
Inhibiting prion conversion may prevent fibril formation and disease progression.
