Lin CH, Liao CC, Wang SY, Peng CY, Yeh YC, Chen MY, Chou TY. Comparative O-GlcNAc Proteomic Analysis Reveals a Role of O-GlcNAcylated SAM68 in Lung Cancer Aggressiveness. Cancers 2022 14(1) 35008409
Abstract:
O-GlcNAcylation is a reversible and dynamic post-translational protein modification catalyzed by O-GlcNAc transferase (OGT). Despite the reported association of O-GlcNAcylation with cancer metastasis, the O-GlcNAc proteome profile for cancer aggressiveness remains largely uncharacterized. Here, we report our comparative O-GlcNAc proteome profiling of two differentially invasive lung adenocarcinoma cell lines, which identified 158 down-regulated and 106 up-regulated candidates in highly invasive cells. Among these differential proteins, a nuclear RNA-binding protein, SAM68 (SRC associated in mitosis of 68 kDa), was further investigated. Results showed that SAM68 is O-GlcNAcylated and may interact with OGT in the nucleus. Eleven O-GlcNAcylation sites were identified, and data from mutant analysis suggested that multiple serine residues in the N-terminal region are important for O-GlcNAcylation and the function of SAM68 in modulating cancer cell migration and invasion. Analysis of clinical specimens found that high SAM68 expression was associated with late cancer stages, and patients with high-OGT/high-SAM68 expression in their tumors had poorer overall survival compared to those with low-OGT/low-SAM68 expression. Our study revealed an invasiveness-associated O-GlcNAc proteome profile and connected O-GlcNAcylated SAM68 to lung cancer aggressiveness.

Liu J, Hao Y, Wang C, Jin Y, Yang Y, Gu J, Chen X. An Optimized Isotopic Photocleavable Tagging Strategy for Site-Specific and Quantitative Profiling of Protein O-GlcNAcylation in Colorectal Cancer Metastasis. ACS chemical biology 2022 35254053
Abstract:
O-linked-β-N-acetylglucosamine (O-GlcNAc) glycosylation is a ubiquitous protein post-translational modification of the emerging importance in metazoans. Of the thousands of O-GlcNAcylated proteins identified, many carry multiple modification sites with varied stoichiometry. To better match the scale of O-GlcNAc sites and their dynamic nature, we herein report an optimized strategy, termed isotopic photocleavable tagging for O-GlcNAc profiling (isoPTOP), which enables quantitative and site-specific profiling of O-GlcNAcylation with excellent specificity and sensitivity. In HeLa cells, ∼1500 O-GlcNAcylation sites were identified with the optimized procedures, which led to quantification of ∼1000 O-GlcNAcylation sites with isoPTOP. Furthermore, we apply isoPTOP to probe the O-GlcNAcylation dynamics in a pair of colorectal cancer (CRC) cell lines, SW480 and SW620 cells, which represent primary carcinoma and metastatic cells, representatively. The stoichiometric differences of 625 O-GlcNAcylation sites are quantified. Of these quantified sites, many occur on important regulators involved in tumor progression and metastasis. Our results provide a valuable database for understanding the functional role of O-GlcNAc in CRC. IsoPTOP should be applicable for investigating O-GlcNAcylation dynamics in various pathophysiological processes.

Wang J, Dou B, Zheng L, Cao W, Zeng X, Wen Y, Ma J, Li X. Synthesis of Na2S2O4 mediated cleavable affinity tag for labeling of O-GlcNAc modified proteins via azide-alkyne cycloaddition. Bioorganic & medicinal chemistry letters 2021 48 34229054
Abstract:
A facile and convergent procedure for the synthesis of azobenzene-based probe was reported, which could selectively release interested proteins conducted with sodium dithionite. Besides, the cleavage efficiency is closely associated with the structural features, in which an ortho-hydroxyl substituent is necessary for reactivity. In addition, the azobenzene tag applied in the Ac4GlcNAz-labled proteins demonstrated high efficiency and selectivity in comparison with Biotin-PEG4-Alkyne, which provides a useful platform for enrichment of any desired bioorthogonal proteomics.

Ramirez DH, Yang B, D'Souza AK, Shen D, Woo CM. Truncation of the TPR domain of OGT alters substrate and glycosite selection. Analytical and bioanalytical chemistry 2021 34725712
Abstract:
O-GlcNAc transferase (OGT) is an essential enzyme that installs O-linked N-acetylglucosamine (O-GlcNAc) to thousands of protein substrates. OGT and its isoforms select from these substrates through the tetratricopeptide repeat (TPR) domain, yet the impact of truncations to the TPR domain on substrate and glycosite selection is unresolved. Here, we report the effects of iterative truncations to the TPR domain of OGT on substrate and glycosite selection with the model protein GFP-JunB and the surrounding O-GlcNAc proteome in U2OS cells. Iterative truncation of the TPR domain of OGT maintains glycosyltransferase activity but alters subcellular localization of OGT in cells. The glycoproteome and glycosites modified by four OGT TPR isoforms were examined on the whole proteome and a single target protein, GFP-JunB. We found the greatest changes in O-GlcNAc on proteins associated with mRNA splicing processes and that the first four TPRs of the canonical nucleocytoplasmic OGT had the broadest substrate scope. Subsequent glycosite analysis revealed that alteration to the last four TPRs corresponded to the greatest shift in the resulting O-GlcNAc consensus sequence. This dataset provides a foundation to analyze how perturbations to the TPR domain and expression of OGT isoforms affect the glycosylation of substrates, which will be critical for future efforts in protein engineering of OGT, the biology of OGT isoforms, and diseases associated with the TPR domain of OGT.
