Figure 1.

Comparison of the distribution of GFP-tagged proteins to different subcellular organelles as determined in three different studies [9-11]. The percentage of proteins localizing to the cytoplasm, nucleus, endoplasmic reticulum (ER) and Golgi are shown as example compartments. The data are taken for yeast cells [10,11] and for mammalian cells [9]. In [10] Golgi localization was not determined.
