Protein and Protein Structure

90.8K
Proteins are one of the most abundant organic molecules in living systems and have the most diverse range of functions of all macromolecules. Proteins may be structural, regulatory, contractile, or protective. They may serve in transport, storage, or membranes; or they may be toxins or enzymes. Their structures, like their functions, vary greatly. They are all, however, amino acid polymers arranged in a linear sequence.
A protein's shape is critical to its function. For example, an enzyme...

Protein Networks02:26

Protein Networks

4.6K
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 Organization

9.9K
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-protein Interfaces

14.9K
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...

  • Bioinformatics
  • Computational Biology
  • Genomics

Background:

  • Understanding protein function is crucial for personalized medicine, agriculture, and therapeutics.
  • Experimental methods for protein function determination are costly and time-consuming.

  • To propose a three-way decision-making framework for enhanced protein function prediction.

Main Methods:

  • Utilized probabilistic rough sets, specifically Game-Theoretic Rough Sets (GTRS) and Information-Theoretic Rough Sets (ITRS), for three-way decisions.
  • Developed an architecture for protein function classification using these probabilistic rough set models.
  • Applied the approach to Saccharomyces cerevisiae data from UniProt and Gene Ontology (GO) databases.

Main Results:

  • The proposed three-way decision approach effectively classifies protein functions.
  • Increasing levels of biological information led to a reduction in deferred cases.
