Word History

Etymology

prote(in) + -ome (in genome)

Note: The term was first used in print in Valerie C. Wasinger, et al., "Progress with gene-product mapping of the Mollicutes: Mycoplasma genitalium," Electrophoresis, vol. 16, no. 7 (July, 1995), pp. 1090-94. According to Wikipedia (as of 6/30/21), proteome was coined by the Australian geneticist Marc R. Wilkins; see Marc R. Wilkins, et al., "Progress with Proteome Projects: Why All Proteins Expressed by a Genome Should be Identified and How To Do It," Biotechnology and Genetic Engineering Reviews, vol. 13 (1996), pp. 19-50; and Marc R. Wilkins, et al., "From Proteins to Proteomes: Large Scale Protein Identification by Two-Dimensional Electrophoresis and Amino Acid Analysis," Nature Biotechnology, vol. 14, issue 1 (January, 1996), pp. 61-65.
