Definition

A proteome is the ensemble of proteins expressed in a given system at a given time and under specific conditions. The system can be an entire ecosystem, a population of a single species, an organism, a specific tissue, a cell culture, a cell, a subpart of a cell, or any other system that partly consists of proteins. The given time can be the lifetime of an individual, a specific steady state (homeostasis), or a short time interval. The proteome can also include all protein forms that constitute the system, meaning that post-translational modifications would be enough to constitute a different proteome.

Example

All the proteins expressed by yeast as measured and described in de Godoy et al. (2008) or Picotti et al. (2009) produced using various mass spectrometry techniques.
