Burt RA, Dejanovic B, Peckham HJ, Lee KA, Li X, Ounadjela JR, Rao A, Malaker SA, Carr SA, Myers SA. Novel Antibodies for the Simple and Efficient Enrichment of Native O-GlcNAc Modified Peptides. Molecular & cellular proteomics : MCP 2021 20 34678516
Abstract:
Antibodies against posttranslational modifications (PTMs) such as lysine acetylation, ubiquitin remnants, or phosphotyrosine have resulted in significant advances in our understanding of the fundamental roles of these PTMs in biology. However, the roles of a number of PTMs remain largely unexplored due to the lack of robust enrichment reagents. The addition of N-acetylglucosamine to serine and threonine residues (O-GlcNAc) by the O-GlcNAc transferase (OGT) is a PTM implicated in numerous biological processes and disease states but with limited techniques for its study. Here, we evaluate a new mixture of anti-O-GlcNAc monoclonal antibodies for the immunoprecipitation of native O-GlcNAcylated peptides from cells and tissues. The anti-O-GlcNAc antibodies display good sensitivity and high specificity toward O-GlcNAc-modified peptides and do not recognize O-GalNAc or GlcNAc in extended glycans. Applying this antibody-based enrichment strategy to synaptosomes from mouse brain tissue samples, we identified over 1300 unique O-GlcNAc-modified peptides and over 1000 sites using just a fraction of sample preparation and instrument time required in other landmark investigations of O-GlcNAcylation. Our rapid and robust method greatly simplifies the analysis of O-GlcNAc signaling and will help to elucidate the role of this challenging PTM in health and disease.

The New Chemical Reporter 6-Alkynyl-6-deoxy-GlcNAc Reveals O-GlcNAc Modification of the Apoptotic Caspases That Can Block the Cleavage/Activation of Caspase-8. Journal of the American Chemical Society 2017 139(23) 28528544
Abstract:
O-GlcNAc modification (O-GlcNAcylation) is required for survival in mammalian cells. Genetic and biochemical experiments have found that increased modification inhibits apoptosis in tissues and cell culture and that lowering O-GlcNAcylation induces cell death. However, the molecular mechanisms by which O-GlcNAcylation might inhibit apoptosis are still being elucidated. Here, we first synthesize a new metabolic chemical reporter, 6-Alkynyl-6-deoxy-GlcNAc (6AlkGlcNAc), for the identification of O-GlcNAc-modified proteins. Subsequent characterization of 6AlkGlcNAc shows that this probe is selectively incorporated into O-GlcNAcylated proteins over cell-surface glycoproteins. Using this probe, we discover that the apoptotic caspases are O-GlcNAcylated, which we confirmed using other techniques, raising the possibility that the modification affects their biochemistry. We then demonstrate that changes in the global levels of O-GlcNAcylation result in a converse change in the kinetics of caspase-8 activation during apoptosis. Finally, we show that caspase-8 is modified at residues that can block its cleavage/activation. Our results provide the first evidence that the caspases may be directly affected by O-GlcNAcylation as a potential antiapoptotic mechanism.
