Abstract

The recent finding that the human genome comprises between 21000 and 39000 genes, a number much lower than expected, has in no way simplified the complexity associated with the understanding of how cells perform their functions. Elucidation of the molecular mechanisms underlying cell functions will require a global knowledge of the expressed proteins, including splice variant products, their post-translational modifications, their subcellular localizations and their assembly into molecular machines as deduced from protein-protein interactions, at any given time during the life of the cell or under any cellular conditions. Current and expected advances in mass spectrometry and bioinformatics might help the realization of these goals in a shorter time than is currently predicted.
