Purpose of the Study:
- To present a computational protocol for identifying chaperone functional modules.
- To determine pathway relationships among chaperones based on physical interactions.
- To organize chaperones into functional groups involved in protein folding.
Main Methods:
- Utilizing physical interaction data from high-throughput proteomic experiments.
- Identifying shared interacting proteins to group chaperones into functional modules.
- Analyzing whole-genome expression and cellular pathways to determine chaperone pathway probabilities.
Main Results:
- A computational protocol for organizing chaperones into functional modules was established.
- The protocol can differentiate between single and multiple folding pathways for substrate proteins.

02:26Protein Networks
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,...

02:04Protein-protein Interfaces
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 polypeptide...
03:00Molecular Chaperones and Protein Folding
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.
