Systems biology Advances in the understanding of biological systems and in the computational interpretation of those systems have enabled biologists to program mammalian cells. The cells shown were programmed to calculate basic logical operations, thanks to a highly complex artificial gene network.

In the context of systems biology, proteomics is the study of the proteome, which represents the complete set of proteins encoded by an organism's genome.1

Proteomics contributes to our understanding of biological systems by defining the full range of cellular functions utilized by an organism. Because the presence and activity of proteins are dynamic, proteomics allows researchers to identify specific proteins produced at particular times, within specific tissues, or during the progression of diseases.1

By mapping these protein sets, scientists can better understand how genetic information is translated into functional biological processes. This data is essential for identifying potential targets for therapeutic drugs and for gaining a broader, systemic view of how an organism functions beyond the level of individual genes.1
