Multiple reaction monitoring (MRM) mass spectrometry has been successfully applied to monitor targeted proteins in biological specimens, raising the possibility that assays could be configured to measure all human proteins. We report the results of a pilot study designed to test the feasibility of a large-scale, international effort for MRM assay(More)
Somatic mutations have been extensively characterized in breast cancer, but the effects of these genetic alterations on the proteomic landscape remain poorly understood. Here we describe quantitative mass-spectrometry-based proteomic and phosphoproteomic analyses of 105 genomically annotated breast cancers, of which 77 provided high-quality data. Integrated(More)
Cell-cycle progression is regulated by the cyclin-dependent kinase (Cdk) family of protein kinases, so named because their activation depends on association with regulatory subunits known as cyclins. Cyclin E normally accumulates at the G1/S boundary, where it promotes S phase entry and progression by activating Cdk2. In normal cells, cyclin E/Cdk2 activity(More)
