Comprehensive Glycoproteomic Tool Development for Cancer Biomarkers

项目总结

Project Summary Glycosylation is one of the most prevalent and important post-translational modifications of proteins, yet it is also one of the most difficult to study. No single method nor analytical platform can give complete information about the glycosylation in a protein sample, and the analytical methods in current use include both ESI and MALDI single and tandem mass spectrometry, at least four types of liquid chromatography, iterative enzyme analysis, glycan-binding experiments with fluorescence read-out, and new methods such as ion mobility spectrometry. There is currently no software platform that can integrate even two of these different data channels. In this project we propose to build a software product called GlycoForm that will be capable of analyzing, visualizing, and integrating glycosylation data over multiple channels. GlycoForm will be able to identify released glycans to the level of detail warranted by the evidence and quantify them using either mass spectrometry or fluorescence signals. The software will include both an interactive user interface for expert inspection, and also customized and automated glycosylation reports for sharing and archiving. The initial release of GlycoForm will handle single and tandem mass spectrometry, chromatographic elution time, and glycan-binding experiments; other data channels will be added later in response to customer demand.
