Stable Isotope Labeling by Amino Acids in Cell Culture (SILAC) Technology in Fission Yeast.
Shotgun proteomics combined with stable isotope labeling by amino acids in cell culture (SILAC) is a powerful approach to quantify proteins and posttranslational modifications across the entire proteome. SILAC technology in  Schizosaccharomyces pombe  must cope with the "arginine conversion problem," in which isotope-labeled arginine is converted to other amino acids. This can be circumvented by either using stable isotope-marked lysine only (as opposed to the more standard lysine/arginine double labeling) or using yeast genetics to create strains that only very inefficiently convert arginine. Both strategies have been used successfully in large-scale (phospho)proteomics projects in  S. pombe  Here we introduce methods for performing a typical SILAC-based experiment in fission yeast, including generation of SILAC-compatible strains, sample preparation, and measurement by mass spectrometry.
