Quantitating the complete human proteome
This is an illustration of SRM peaks and a human face. Reporting in the journal Cell, Senior Research Scientist Dr. Ulrike Kusebauch, of Institute for Systems Biology (ISB), describes the results of a collaboration between scientists at ISB, ETH Zurich and a number of other contributing institutes to develop the Human SRMAtlas, a compendium of proteomic assays for any human protein. The Human SRMAtlas is a compendium of highly specific mass spectrometry assays for the targeted identification and reproducible quantification of any protein in the predicted human proteome, including assays for many spliced variants, non-synonymous mutations and post-translational modifications. Using the technique called selected reaction monitoring, assays were developed with the use of 166,174 well-characterized, chemically synthesized proteotypic peptides. The SRMAtlas resource is freely publicly available at http://www.srmatlas.org and will equally benefit focused, hypothesis-driven and large proteome-scale studies. We expect this resource will significantly advance protein-based experimental biology to...
