With the DNA sequences of more than 90 genomes completed, as well as a draft sequence of the human genome, a major challenge in modern biology is to understand the expression, function, and regulation of the entire set of proteins encoded by an organism—the aims of the new field of proteomics. This information will be invaluable for understanding how complex biological processes occur at a molecular level, how they differ in various cell types, and how they are altered in disease states. The term proteomics describes the study and characterization of a complete set of proteins present in a cell, organ, or organism at a given time.
In general, proteomic approaches can be used (a) for proteome profiling, (b) for comparative expression analysis of two or more protein samples, (c) for the localization and identification of posttranslational modifications, and (d) for the study of protein-protein interactions. The human genome harbours 26000–31000 protein-encoding genes; whereas the total number of human protein products, including splice variants and essential posttranslational modifications (PTMs), has been estimated to be close to one million. It is evident that most of the functional information on the genes resides in the proteome, which is the sum of multiple dynamic processes that include protein phosphorylation, protein trafficking, localization, and protein-protein interactions. Moreover, the proteomes of mammalian cells, tissues, and body fluids are complex and display a wide dynamic range of proteins concentration one cell can contain between one and more than 100000 copies of a single protein.
A rapidly emerging set of key technologies is making it possible to identify large numbers of proteins in a mixture or complex, to map their interactions in a cellular context, and to analyze their biological activities. Mass spectrometry has evolved into a versatile tool for examining the simultaneous expression of more than 1000 proteins and the identification and mapping of posttranslational modifications. High-throughput methods performed in an array format have enabled large-scale projects for the characterization of protein localization, protein-protein interactions, and the biochemical analysis of protein function. Finally, the plethora of data generated in the last few years has led to approaches for the integration of diverse data sets that greatly enhance our understanding of both individual protein function and elaborate biological processes.
