Method Abstract: "[Investigators] used fluorescence microscopy to measure global and local concentrations of 28 cytoskeletal and signaling proteins fused to yellow fluorescent protein (YFP) in the fission yeast Schizosaccharomyces pombe. Native promoters controlled the expression of these functional YFP fusion proteins. Fluorescence measured by microscopy or flow cytometry was directly proportional to protein concentration measured by quantitative immunoblotting."
Comments P.312 middle column 2nd paragraph: "Global cytoplasmic concentrations of cytokinesis proteins (Table 1) range from 0.04 μM formin Cdc12p (600 molecules per cell) to 63.2 μM actin (1.43 million molecules per cell). The concentration of myosin-II light chain Cdc4p (4.8 μM) is 10-fold higher than that of Myo2p (0.45 μM), which is in keeping with evidence for functions beyond its partnership with myosins (refs 11–14). Most of the proteins studied are more abundant in S. pombe than in haploid strains of S. cerevisiae (table S2), in part because of the 1.7-fold higher protein content per cell of S. pombe (See the fission yeast handbook (available at ) & primary source S[24])."
