Proteomics01:33

Proteomics

7.3K
A proteome is the entire set of proteins that a cell type produces. We can study proteomes using the knowledge of genomes because genes code for mRNAs, and the mRNAs encode proteins. Although mRNA analysis is a step in the right direction, not all mRNAs are translated into proteins.
Proteomics is the study of proteomes' function. It involves the large-scale systematic study of the proteome to denote the protein complement expressed by a genome. Scientist Mark Wilkins coined the term...

Protein Networks02:26

Protein Networks

4.0K
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,...

Protein-protein Interfaces

12.5K
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...

    Background:

    • Identifying conserved 3D protein patterns aids polypharmacological drug design.
    • Existing tools have limitations, focusing only on known binding sites or motifs.
    • These tools fail to compare all potential orthosteric and allosteric binding sites.

    Purpose of the Study:

    • To enhance the performance of the Geomfinder algorithm for large-scale protein structure comparison.
    • To develop parallel versions of Geomfinder for various computing architectures.
    • To enable efficient identification of structural similarities across all potential binding sites.

    Main Methods:

    • Developed parallel versions of the Geomfinder algorithm.
    • Implemented optimizations for Symmetric Multiprocessing (SMP) systems.
