Proteins complement expressed by a genome or tissue --Wilkins et at. 1995 BiotechnologyAndGeneticEngineeringReviews 12, 19-50

특정개체의 특정상태에서의 모든 [Proteins], [Genome]이 모든 cell이 가지고 있는 같은 정보임에 비해, [Proteome]은 cell specific한 정보이다.

While [Genome] is a static repository of information whose contents do not change with time, the [Proteome] is highly dynamic, with the subset of [Proteins] expressed changing from moment to moment according to the developmental and physiological state of the cell. -- in ProteomicsFromProteinSequenceToFunction

Proteomes change as a function of:

• time
• development
• intracellular
• extracellular
