An integrated human kinase network

Description

Protein physical interactions (PPIs), typically taking place in protein complexes, have proved to be useful to functionally associate proteins or genes in a broad range of studies. Additional physical interactions, such as enzyme-substrate, also inform on functional relationships. Furthermore, therapeutic agents such as small molecules or antibodies can be regarded as inducers of perturbations in cellular networks, thus linking information related to drug targets and protein interaction networks naturally.

Here, we provide a compilation of an important corpus of physical interaction data extracted from large public data collections. The collected interactions fall in three different categories:

All together, the integration of PPI, KSI and DPI in large numbers provides the opportunity to study proteins or their coding genes in a broad functional context, and to further connect them with potential FDA-approved or tool compounds.

The integrated PPI network has been maintained and updated at CeMM over several years and the recent addition of KSIs and DPIs was undertaken during a study we published recently about kinase networks: Colinge et al., "Building and exploring and integrated human kinase network: Global organization and medical entry points", J.Proteomics, 2014.

In the future, we plan to complement this database with additional enzyme-substrate interactions, bioinformatics tools, and the generation of an equivalent mouse network. Release frequency is every six months.
