The concept of proteome was first proposed by Marc Wilkins. It refers to all the proteins expressed by a genome (Genome), or a cell or tissue. The concept of proteome has many differences with the concept of genome. The organization and even the state of the environment change. During transcription, a gene can be spliced in multiple mRNA forms. A proteome is not a direct product of a genome. The number of proteins in the proteome can sometimes exceed the number of genomes. Proteomics is in an early "development" state. Experts in this field deny that it is a pure methodology. Just like genomics, it is not a closed, conceptualized and stable knowledge system, but a field.
