Proteomics is the large-scale study of proteins. Proteins are vital parts of living organisms, with many functions. The proteome is the entire set of proteins produced or modified by an organism or system. Proteomics enables the identification of ever-increasing numbers of proteins. This varies with time and distinct requirements, or stresses, that a cell or organism undergoes.[3] Proteomics is an interdisciplinary domain that has benefitted greatly from the genetic information of various genome projects, including the Human Genome Project. It covers the exploration of proteomes from the overall level of protein composition, structure, and activity, and is an important component of functional genomics. Proteomics generally refers to the large-scale experimental analysis of proteins and proteomes, but often refers specifically to protein purification and mass spectrometry. The most significant breakthrough in proteomics has been the mass spectrometric identification of gel-separated proteins.
