项目摘要
We propose to optimize and disseminate targeted mass spectrometric workflows for the quantification of
glycopeptides and software for data interpretation. Recent developments enable efficient SWATH DIA of
glycopeptides under adjusted fragmentation conditions. The sensitivity of these assays can be further
improved in targeted LC-MS/MS-MRM and HR-PRM workflows. We will generate a knowledgebase of
glycopeptides and the transitions needed for the development and application of the targeted glycopeptide
quantification workflows. We will generate software tools necessary to develop glycopeptide transitions and
analyze spectra from targeted quantification workflows with respect to these glycopeptide transitions. We will
also make the analytical protocols for the development of targeted workflows for glycopeptide SWATH DIA,
HR-PRM, and LC-MS/MS-MRM assays available to the research community. The availability of targeted
quantification resources will enable, for the first time, exploration of glycoproteins in the context of disease
pathophysiology by the broad research community. Furthermore, mass spectrometric assays for quantification
of site specific protein glycoforms will drive research in the characterization of glycosylation pathways and
systems glycoscience. Reliable quantification of site-specific glycoproteoforms will begin a new era of targeted
clinical assays that have the potential to change the current diagnostic paradigm and to identify new
therapeutic targets among the many glycoprotein targets that remain largely unexplored.
