Protein Networks02:26

Protein Networks

4.5K
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 Interfaces02:04

Protein-protein Interfaces

14.7K
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 and Protein Structure02:15

Protein and Protein Structure

87.4K
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...

The Evidence for Evolution02:55

The Evidence for Evolution

48.0K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Intrinsically Disordered Proteins02:18

Intrinsically Disordered Proteins

19.4K
Intrinsically disordered proteins are a group of proteins that do not fold into specific three-dimensional structures. Their structural flexibility allows them to complement ordered proteins to perform functions that are inaccessible to rigid structures. They are more common in eukaryotes than prokaryotes and may either be exclusively intrinsically disordered or hybrid proteins, consisting of a mix of ordered and disordered regions. The absence of a rigid structure in these proteins can be...

Area of Science:

  • Molecular Biology
  • Bioinformatics
  • Systems Biology

Background:

  • Protein-protein interactions (PPIs) are fundamental to cellular processes.
  • Comprehensive databases of PPIs are essential for understanding biological networks.
  • Existing databases often lack unified data and precise experimental evidence.

Purpose of the Study:

  • To update and enhance the APID Interactomes database.
  • To provide a more precise and curated collection of protein interactomes.
  • To improve the integration and avoid duplication of PPI data.

Main Methods:

  • Integrated PPIs from five primary databases (BioGRID, DIP, HPRD, IntAct, MINT).
  • Included data from human systematic sources and Protein Data Bank (PDB) files.
  • Classified interaction detection methods into 'binary' and 'indirect' types.

Main Results:

  • APID Interactomes now covers over 1100 organisms, with 30 species having >500 interactions.
  • Redefined PPI properties for more precise data integration and reduced false duplicates.
  • Provides unified interactomes with specific experimental evidence, distinguishing binary interactions.

Conclusions:

  • The updated APID database offers a more accurate and comprehensive resource for studying protein interaction networks.
  • Enhanced data integration and evidence classification facilitate deeper biological exploration.
  • APID serves as a valuable public resource for researchers in molecular biology and bioinformatics.
