Protein interaction maps for model organisms

Until recently. classical genetics and biochemistry were the main technique s used to investigate how organisms develop, reproduce, behave and age. But with the availability of complete genome sequences new approaches are emer ging. Complete sets of proteins 'proteomes' - can be predicted from genome sequences and used to characterize protein functions globally. For example. through the large-scale identification of physical protein-protein interac tions, comprehensive protein interaction maps are being generated. And thes e maps might help us to understand the processes that control the biology o f living organisms.
