Proteomics is the large-scale study of proteins.[1][2] Proteins are vital parts of living organisms, with many functions. The term proteomics was coined in 1997,[3] in analogy to genomics, the study of the genome. The word proteome is a portmanteau of protein and genomeThe proteome is the entire set of proteins that is produced or modified by an organism or system. Proteomics has enabled the identification of ever increasing numbers of protein.
