Lei C, Chen Z, Hao Y, Huang W, Chu T, Xiao K, Zhang C, Zhou W, Li C, Chen X. Quantitative and site-specific chemoproteomic profiling of O-GlcNAcylation in Drosophila. Bioorganic & medicinal chemistry 2025 124 40245499
Abstract:
Protein O-GlcNAcylation plays a crucial role in Drosophila melanogaster development. Dysregulation of O-GlcNAc transferase (sxc/Ogt) and O-GlcNAcase (Oga) disrupts early embryogenesis and locomotor behavior. It is therefore of great interest to identify and quantitatively analyze O-GlcNAcylation sites in Drosophila. Here, we perform quantitative and site-specific profiling of O-GlcNAcylation in Drosophila by employing a chemoenzymatic labeling strategy. A total of 2196 unambiguous O-GlcNAcylation sites and 1308 O-GlcNAcylated proteins are identified. Quantitative analysis of O-GlcNAcylation in the head of Drosophila with sxc/Ogt knockdown in GABAergic neurons reveals a reduction in O-GlcNAcylation of several proteins involved in muscle development, consistent with the phenotypic defects observed in sxc/Ogt RNAi Drosophila. Furthermore, quantitative analysis of O-GlcNAcylation under a high-sugar diet reveals altered O-GlcNAcylation of several proteins associated with obesity and neurological diseases, such as Hex-A and Ankyrin 2. Our study not only establishes an effective method for large-scale identification of O-GlcNAcylation sites, but also provides a valuable resource for studying O-GlcNAc biology in Drosophila.

Akan I, Halim A, Vakhrushev SY, Clausen H, Hanover JA. Drosophila O-GlcNAcase Mutants Reveal an Expanded Glycoproteome and Novel Growth and Longevity Phenotypes. Cells 2021 10(5) 33925313
Abstract:
The reversible posttranslational O-GlcNAc modification of serine or threonine residues of intracellular proteins is involved in many cellular events from signaling cascades to epigenetic and transcriptional regulation. O-GlcNAcylation is a conserved nutrient-dependent process involving two enzymes, with O-GlcNAc transferase (OGT) adding O-GlcNAc and with O-GlcNAcase (OGA) removing it in a manner that's protein- and context-dependent. O-GlcNAcylation is essential for epigenetic regulation of gene expression through its action on Polycomb and Trithorax and COMPASS complexes. However, the important role of O-GlcNAc in adult life and health span has been largely unexplored, mainly due the lack of available model systems. Cataloging the O-GlcNAc proteome has proven useful in understanding the biology of this modification in vivo. In this study, we leveraged a recently developed oga knockout fly mutant to identify the O-GlcNAcylated proteins in adult Drosophilamelanogaster. The adult O-GlcNAc proteome revealed many proteins related to cell and organismal growth, development, differentiation, and epigenetics. We identified many O-GlcNAcylated proteins that play a role in increased growth and decreased longevity, including HCF, SIN3A, LOLA, KISMET, ATX2, SHOT, and FOXO. Interestingly, oga mutant flies are larger and have a shorter life span compared to wild type flies, suggesting increased O-GlcNAc results in increased growth. Our results suggest that O-GlcNAc alters the function of many proteins related to transcription, epigenetic modification and signaling pathways that regulate growth rate and longevity. Therefore, our findings highlight the importance of O-GlcNAc in growth and life span in adult Drosophila.
