Interactomics Interactomics What? • Describes networks of interactions between biomolecules • Most comonly: protein-protein interactions (PPIs) networks e.g. metabolic, signaling pathways Why? • Network medicine: predict how a network reacts to perturbations (e.g. the removal of a protein or an Interaction, due to mutations) → Identify biomarkers of diseases and drug targets How? • Experimental techniques (Y2H, AP-MS…) → Limitations: • PPIs detection threshold • Homomultimers undetected • Interacting regions unknown
