Proteomics Core Unit

Head of Unit:  Javier Muñoz

Proteins are the molecular effectors of cells and catalyse almost all biological processes. The levels of protein abundance, together with their modification states and interactions, adapt dynamically to external or internal (genetic) stimuli and thus define the cell’s functional state and determine its phenotype. Mass spectrometrybased proteomics is the most powerful tool to study the proteome, providing fundamental information of basic biology. In addition, recent improvements in sensitivity and throughput now allow the analysis of larger cohorts of samples including biopsies, thus fully integrating proteomics into the clinical research toolbox. All these efforts have led to the provision of new insights into the molecular mechanisms underlying cancer development as well as the identification of novel biomarkers.
