Proteomics 4D: The proteome in context

Project description

Proteome analysis of multi-protein modules

Cellular proteins are arranged in a network consisting of interconnected multi-protein modules which play a crucial role in shaping complex phenotypes. Proteomic approaches so far have focused on the identification and quantitation of large numbers of proteins as independent entities. The EU-funded PROTEOMICS4D project proposes to analyse protein modules instead, hoping to provide new insights and opportunities to uncover the intricate relationship between genetic factors and disease phenotypes. The work will focus on protein kinase modules due to their established connection with cancer. Subsequently, the project aims to develop a more versatile platform for unveiling the impact of disease-associated mutations on proteome organisation and the development of complex diseases.

Objective

Elements operating in the context of a system generate results that are different from the simple addition of the results of each element. This notion is one of the basic tenants of systems science. In systems biology/medicine complex (disease) phenotypes arise from multiple interacting factors, specifically proteins. Yet, the biochemical and mechanistic base of complex phenotypes remain elusive.
An array of powerful genomic technologies including GWAS, WGS, transcriptomics, epigenetic analyses and proteomics have identified numerous factors that contribute to complex phenotypes. It can be expected that over the next few years, genetic factors contributing to specific complex phenotypes will be comprehensively identified, while their interactions will remain elusive.
The project “Proteomics 4D: The proteome in context “explores the concept, that complex phenotypes arise from the perturbation of modules of interacting proteins and that these modules integrate seemingly independent genomic variants into a single biochemical response. We will develop and apply a generic technology to directly measure the composition, topology and structure of wild type and genetically perturbed protein modules and relate structural changes to their functional output.
This will be achieved by a the integration of quantitative proteomic and phosphoproteomic technologies determining molecular phenotypes, and hybrid structural methods consisting of chemical cross-linking and mass spectrometry, cryoEM and computational data integration to probe structural perturbations.
The project will focus initially on the structural and functional effects of cancer associated mutations in protein kinase modules and then generalize to study perturbed modules in any tissue and disease state. The resources supporting this technology will be disseminated to catalyze a broad transformation of biology and molecular medicine towards the analysis of the proteome as a modular entity, the proteome in context.
