Protein Networks02:26

Protein 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,...

Proteomics01:33

Proteomics

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...

Area of Science:

  • Systems Biology
  • Bioinformatics
  • Computational Biology

Background:

  • Automated integration of scientific knowledge relies on programmatic access to biological databases.
  • Static data downloads lack full database functionality, while webservices can be computationally intensive.
  • Existing methods for accessing biological data have limitations in functionality and resource consumption.

Purpose of the Study:

  • To develop a versatile Application Programming Interface (API) for the MetNetDB database.
  • To provide programmatic access to biological network data, including molecular entities, interactions, and pathways.
  • To offer a flexible and resource-efficient alternative to data dumps and webservices for systems biology applications.

Main Methods:

  • Developed MetNetAPI, an Application Programming Interface (API) for the MetNetDB database.
  • Implemented data retrieval across four layers: molecular entities, localized entities, interactions, and pathways.
  • Enabled intuitive navigation between data layers and customized data retrieval through Network objects.

Main Results:

  • MetNetAPI abstracts database operations, allowing independent application of functions to datasets.
  • Data is accessible in four intuitive layers, facilitating navigation and complex queries.
  • Customizable data retrieval and network construction capabilities are provided, with limited computational demand on the host server.

Conclusions:

  • MetNetAPI offers advantages for systems biology platforms by providing live database access and analytical functions.
  • It serves as a thin server/fat client setup, requiring limited server-side resources.
  • The API is available for Java, .NET, and R, supporting flexible data retrieval and user-defined network manipulation.
