- (biochemistry) The branch of molecular biology that studies the set of proteins expressed by the genome of an organism.
- 1998, N. Leigh Anderson, “Proteome and proteomics: New technologies, new concepts, and new words”, in Electrophoresis, volume 19, page 1853:
- The derived word "proteomics", which has come into use almost as an afterthought, may be equally useful since it indicates something less well-defined but more ambitious. Proteomics is a field, just as genomics is, rather than a closed and conceptually static body of knowledge (as are the genome and proteome, by definition).
