2.4.1.255 analysis application of a high-throughput OGT assay to a library of peptides 736868 2.4.1.255 analysis metabolic labeling method to introduce the diazirine photocross-linking functional group onto O-GlcNAc residues in mammalian cells. Cells are engineered to produce diazirine-modified UDP-GlcNAc (UDP-Glc-NDAz), which is transferred to substrate proteins by endogenous OGT, producing O-GlcNDAz. Modified proteins can be covalently cross-linked to their binding partners, providing information about O-GlcNAc-dependent interactions 736484 2.4.1.255 analysis peptide microarray approach to discover novel OGT substrates and study its specificity 737097 2.4.1.255 analysis single-well OGT enzyme assay that utilizes His6-tagged substrates, a chemoselective chemical reaction, and unpurified OGT. The high-throughput Ni-nitrilotriacetic acid plate OGT assay facilitates discovery of OGT-specific inhibitors on versatile substrates and the characterization of new enzyme variants 735732 2.4.1.255 medicine pharmacological inhibition of OGT in breast cancer cells has similar anti-growth and anti-invasion effects. OGT may represent novel therapeutic targets for breast cancer 706017 2.4.1.255 medicine the neurodegenerative disease protein ataxin-10 (Atx-10) is associated with cytoplasmic OGT p110 in the brain 674603
