TranscriptomicsConserved nutrient sensor O-GlcNAc transferase is integral to the C. elegans pathogen-specific immune response
Discriminating pathogenic bacteria from energy-harvesting commensals is key to host immunity. Using mutants defective in the enzymes of O-linked N-acetylglucosamine (O-GlcNAc) cycling, we examined the role of this nutrient-sensing pathway in the Caenorhabidits elegans innate immune response. Using w...

ProteomicsQuantitative Proteomics Reveals that the OGT Interactome is Remodeled in Response to Oxidative Stress
The dynamic modification of specific serine and threonine residues of intracellular proteins by O-linked N-acetyl-β-D-glucosamine (O-GlcNAc) mitigates injury and promotes cytoprotection in a variety of stress models. The O-GlcNAc transferase (OGT) and the O-GlcNAcase (OGA) are the sole enzymes that ...

ProteomicsThe OGT TPR Interactome defined by BioID
BioID performed in HeLa cells for the TPR domain of The O-GlcNAc Transferase and eGFP (negative control). Used to determine TPR interactors and the TPR interactome in HeLa cells. Three biological replicates were performed, with each replicate having an experimental (TPR-BirA*) and negative (eGFP-Bir...

GenomicsOGT, H2B S112GlcNAc, TET2 ChIP-seq results
TET2 directly interacts with OGT, which is important for the chromatin association of OGT in vivo. Although this specific interaction does not regulate the enzymatic activity of TET2, it facilitates OGT-dependent histone O-GlcNAcylation. Moreover, OGT associates with TET2 at transcription starting s...

TranscriptomicsExpression from C. elegans L1 animals
Nutrient-driven O-GlcNAcylation of key components of the transcription machinery may epigenetically modulate gene expression in metazoans. Knockouts of the O-GlcNAc cycling enzymes in C. elegans are viable and fertile, allowing a global analysis of the impact of GlcNAcylation. Whole genome transcrip...

TranscriptomicsGlycosylation regulates the stability of c-MYC
Tumorigenesis is characterised by changes in transcriptional regulation and the androgen receptor (AR) has been identified as a key driver in prostate cancer. In this study, we show that the hexosamine biosynthetic pathway (HBP) genes are overexpressed in clinical prostate cancer and androgen-regula...

TranscriptomicsDrosophila Oga deletion perturbs O-GlcNAcylation of chromatin factors
Drosophila development is a complex and dynamic process regulated, in part, by members of the Polycomb (Pc), Trithorax (Trx) and Compass chromatin modifier complexes. O-GlcNAc Transferase (OGT/SXC) is essential for Pc repression suggesting that the O-GlcNAcylation of proteins plays a key role in re...
