摘要
Proteins directly carry out and regulate cellular functions. As a result, changes in protein levels within a cell directly influence cellular processes. Similarly, it is intuitive that the intracellular localization of proteins is a key component of their functionality. Optimal activity is achieved by a combination of protein concentration, co-compartmentalization with substrates, co-factors and regulators and sequestration from deleterious locales. The proteome within a cell is highly dynamic and changes in response to different environmental conditions. High-throughput microscopic analysis in the budding yeast Saccharomyces cerevisiae has afforded proteome-wide views of protein organization in living cells, and of how protein abundance and location is regulated and remodeled in response to stress.
