Title	HeLa, HEK293T and mouse lung, heart and spleen LC-MS/MS
Description	Proteins are ubiquitously modified with glycans of varied chemical structures via distinct glycosidic linkages, making the landscape of protein glycosylation challenging to map. Profiling of intact glycopeptides with mass spectrometry (MS) has recently emerged as a powerful tool for revealing matched information of the glycosylation sites and attached glycans (i.e., intact glycosites), which, however, is largely limited to individual glycosylation types. Here, we develop Click-iG, which integrates metabolic labeling of glycans with clickable unnatural sugars, an optimized MS method, and a tailored version of pGlyco3 software to enable simultaneous enrichment and profiling of three types of—N-linked, O-linked, and O-GlcNAcylated—intact glycopeptides. We demonstrated Click-iG by identification of thousands of intact glycosites in cell lines and living mice. From the mouse lung, heart, and spleen, a total of 547 N-glycosylation sites with 161 glycan compositions, 198 O-glycosylation sites with 262 glycans, and 1,947 O‑GlcNAcylation sites were identified. The Click-iG-enabled unprecedent coverage on the protein glycosylation landscape lays the foundation for interrogating crosstalk between different glycosylation pathways.
