Another cool paper in MCP this month is this gem from Udeshi et. al., out of Steven Carr's lab. In this, the group reports their strategy and results from a fully optimized enrichment and analysis procedures for anti-di-glycine remnant studies. The study in question was performed on SILAC labeled cells, demonstrating that these studies can be qualitative or quantitative. All of the MS/MS analyses were performed on a Q Exactive and analyzed with MaxQuant. The end result -- 20,000+ ubiquitination sites that can be identified/quantified in a single experiment.
As we continue to find more and more things that are affected by ubiquitination, I think this is going to be an extremely well cited paper for how to do this kind of study. Definitely check it out!
