Protein Networks

3.6K
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-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...

Proteomics

7.4K
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...

  • Proteomics
  • Systems Biology
  • Bioinformatics

Background:

  • Affinity purification coupled to mass spectrometry (AP-MS) is a key systems biology technique.
  • AP-MS experiments generate large datasets, posing visualization challenges, especially when integrating orthogonal data.

Purpose of the Study:

  • To present a novel visualization tool for AP-MS data.
  • To facilitate the integration and comparison of AP-MS experiments and orthogonal datasets.

Main Methods:

  • Development of Circular Interaction Graph for Proteomics (CIG-P), a Java-based GUI tool.
  • Input of experimental and reference data in CSV format.
  • Generation of interactive circular diagrams, exportable as vector graphics (PDF).

Main Results:

  • CIG-P generates visually appealing circular diagrams for AP-MS data representation.
  • The tool enables the integration of orthogonal datasets, exemplified by PRPF4B kinase data with spliceosome components.
  • Allows for direct comparison between different AP-MS experiments.

Conclusions:

  • CIG-P enhances the presentation of AP-MS data to a wider audience.
