The general goal of proteomics is to monitor the properties of the entire complement of proteins from a given cell or organism, and to determine how these properties change in response to various physiological states, such as signaling ligands, cell cycle, and disease.
Focused proteomics projects may represent a useful way to do limited studies on the way to full proteomics, although they can be informative explorations of specific problems in their own right.
Proteomics aids in the discovery of protein function; it helps in understanding specific biological processes such as apoptosis and the cell cycle, and it helps in developing new tools for diagnosis and therapy.

  Proteomics Summary
Proteomics attempts to characterize proteins, compare variations in their expression levels in normal and disease states, study their interactions with other proteins, and identify their functional roles.
Proteomics is a discipline of microbiology and molecular biology that has arisen from the gene sequencing efforts that culminated in the sequencing of the human genome in the last years of the twentieth century.
Proteomics research often involves the comparison of the proteins produced by a bacterium (example, Escherichia coli) grown at different temperatures, or in the presence of different food sources, or a population grown in the lab versus a population recovered from an infection.

Proteomics includes not only the identification and quantification of proteins, but also the determination of their localization, modifications, interactions, activities, and, ultimately, their function.
Proteomics, like its precursor genomics, thus represents the emergence of a new way of doing research that is not dependent on the testing of specific models of cellular behavior.
Given the current genomic and proteomic commotion, we should keep in mind that a protein found to be "in the spliceosome complex," "interacting with actin," "co-evolving with a prion protein," or "up-regulated in leukemia" has not been functionally characterized in the traditional sense to which biologists are accustomed.

The concept of the proteome is fundamentally different to that of the genome: while the genome is virtually static and can be well defined for an organism, the proteome continually changes in response to external and internal events.
Proteomics is a rapidly evolving field that is rife with commercial opportunities as the technology achieves ever higher throughput at lower cost and greater sensitivity.
The most useful definition of proteomics is likely to be the broadest: proteomics represents the effort to establish the identities, quantities, structures and biochemical and cellular functions of all proteins in an organism, organ, or organelle, and how these properties vary in space, time and physiological state.
