Hou C, Deng J, Wu C, Zhang J, Byers S, Moremen KW, Pei H, Ma J. Ultradeep O-GlcNAc proteomics reveals widespread O-GlcNAcylation on tyrosine residues of proteins. Proceedings of the National Academy of Sciences of the United States of America 2024 121(47) 39531497
Abstract:
As a unique type of glycosylation, O-linked β-N-acetylglucosamine (O-GlcNAc) modification (O-GlcNAcylation) on Ser/Thr residues of proteins was discovered 40 y ago. O-GlcNAcylation is catalyzed by two enzymes: O-GlcNAc transferase (OGT) and O-GlcNAcase (OGA), which add and remove O-GlcNAc, respectively. O-GlcNAcylation is an essential glycosylation that regulates the functions of many proteins in virtually all cellular processes. However, deep and site-specific characterization of O-GlcNAcylated proteins remains a challenge. We developed an ultradeep O-GlcNAc proteomics workflow by integrating digestion with multiple proteases, two mass spectrometric approaches (i.e., electron-transfer/higher-energy collision dissociation [EThcD] and HCD product-dependent electron-transfer/higher-energy collision dissociation [HCD-pd-EThcD]), and two data analysis tools (i.e., MaxQuant and Proteome Discoverer). The performance of this strategy was benchmarked by the analysis of whole lysates from PANC-1 (a pancreatic cancer cell line). In total, 2,831 O-GlcNAc sites were unambiguously identified, representing the largest O-GlcNAc dataset of an individual study reported so far. Unexpectedly, in addition to confirming known sites and identifying many other sites of Ser/Thr modification, O-GlcNAcylation was found on 121 tyrosine (Tyr) residues of 93 proteins. In vitro enzymatic assays showed that OGT catalyzes the transfer of O-GlcNAc onto Tyr residues of peptides and OGA catalyzes its removal. Taken together, our work reveals widespread O-GlcNAcylation on Tyr residues of proteins and that Tyr O-GlcNAcylation is mediated by OGT and OGA. As another form of glycosylation, Tyr O-GlcNAcylation is likely to have important regulatory roles.

Woo CM, Lund PJ, Huang AC, Davis MM, Bertozzi CR, Pitteri SJ. Mapping and Quantification of Over 2000 O-linked Glycopeptides in Activated Human T Cells with Isotope-Targeted Glycoproteomics (Isotag). Molecular & cellular proteomics : MCP 2018 17(4) 29351928
Abstract:
Post-translational modifications (PTMs) on proteins often function to regulate signaling cascades, with the activation of T cells during an adaptive immune response being a classic example. Mounting evidence indicates that the modification of proteins by O-linked N-acetylglucosamine (O-GlcNAc), the only mammalian glycan found on nuclear and cytoplasmic proteins, helps regulate T cell activation. Yet, a mechanistic understanding of how O-GlcNAc functions in T cell activation remains elusive, partly because of the difficulties in mapping and quantifying O-GlcNAc sites. Thus, to advance insight into the role of O-GlcNAc in T cell activation, we performed glycosite mapping studies via direct glycopeptide measurement on resting and activated primary human T cells with a technique termed Isotope Targeted Glycoproteomics. This approach led to the identification of 2219 intact O-linked glycopeptides across 1045 glycoproteins. A significant proportion (>45%) of the identified O-GlcNAc sites lie near or coincide with a known phosphorylation site, supporting the potential for PTM crosstalk. Consistent with other studies, we find that O-GlcNAc sites in T cells lack a strict consensus sequence. To validate our results, we employed gel shift assays based on conjugating mass tags to O-GlcNAc groups. Notably, we observed that the transcription factors c-JUN and JUNB show higher levels of O-GlcNAc glycosylation and higher levels of expression in activated T cells. Overall, our findings provide a quantitative characterization of O-GlcNAc glycoproteins and their corresponding modification sites in primary human T cells, which will facilitate mechanistic studies into the function of O-GlcNAc in T cell activation.

Shen B, Zhang W, Shi Z, Tian F, Deng Y, Sun C, Wang G, Qin W, Qian X. A novel strategy for global mapping of O-GlcNAc proteins and peptides using selective enzymatic deglycosylation, HILIC enrichment and mass spectrometry identification. Talanta 2017 169 28411811
Abstract:
O-GlcNAcylation is a kind of dynamic O-linked glycosylation of nucleocytoplasmic and mitochondrial proteins. It serves as a major nutrient sensor to regulate numerous biological processes including transcriptional regulation, cell metabolism, cellular signaling, and protein degradation. Dysregulation of cellular O-GlcNAcylated levels contributes to the etiologies of many diseases such as diabetes, neurodegenerative disease and cancer. However, deeper insight into the biological mechanism of O-GlcNAcylation is hampered by its extremely low stoichiometry and the lack of efficient enrichment approaches for large-scale identification by mass spectrometry. Herein, we developed a novel strategy for the global identification of O-GlcNAc proteins and peptides using selective enzymatic deglycosylation, HILIC enrichment and mass spectrometry analysis. Standard O-GlcNAc peptides can be efficiently enriched even in the presence of 500-fold more abundant non-O-GlcNAc peptides and identified by mass spectrometry with a low nanogram detection sensitivity. This strategy successfully achieved the first large-scale enrichment and characterization of O-GlcNAc proteins and peptides in human urine. A total of 474 O-GlcNAc peptides corresponding to 457 O-GlcNAc proteins were identified by mass spectrometry analysis, which is at least three times more than that obtained by commonly used enrichment methods. A large number of unreported O-GlcNAc proteins related to cell cycle, biological regulation, metabolic and developmental process were found in our data. The above results demonstrated that this novel strategy is highly efficient in the global enrichment and identification of O-GlcNAc peptides. These data provide new insights into the biological function of O-GlcNAcylation in human urine, which is correlated with the physiological states and pathological changes of human body and therefore indicate the potential of this strategy for biomarker discovery from human urine.
