General description

O-GlcNAc transferase (OGT) catalyzes the addition of an N-acetylglucosamine residue to the amino acids serine or threonine. The enzyme is an homotrimer consisting of three subunits of 110 kDa each, with multiple tetratricopeptide (TPR) repeats.

Immunogen

synthetic peptide corresponding to amino acids 1024-1037 of human O-GlcNAc transferase, conjugated to KLH via an N-terminal added cysteine residue.

Biochem/physiol Actions

O-linked β-N-acetyl glycosamine (O-GlcNAc) is involved in repressing transcription. O-GlcNAc transferase (OGT) interacts with a histone deacetylase complex by binding to the co repressor Sin3A. This interaction leads to the repression of transcription, after transcription factors and RNA polymerase II are modified by addition of O-GlcNAc. O-GlcNAc modification reversibly inhibits proteosomal function in an ubiquitin-independent fashion.

Physical form

Solution in 0.01 M phosphate buffered saline, pH 7.4, and 15 mM sodium azide.

Tumor occurrence and development are closely related to metabolism abnormalities. One of the metabolic networks that is dysregulated during carcinogenesis is the fatty acid synthesis pathway, which is mainly controlled by fatty acid synthase (FASN). We previously demonstrated in proliferating

The nuclear receptor REV-ERBα integrates the circadian clock with hepatic glucose and lipid metabolism by nucleating transcriptional comodulators at genomic regulatory regions. An interactomic approach identified O-GlcNAc transferase (OGT) as a REV-ERBα-interacting protein. By shielding cytoplasmic OGT from proteasomal degradation

O-GlcNAc Transferase (OGT) catalyzes protein O-GlcNAcylation, an abundant and dynamic nuclear and cytosolic modification linked to epigenetic regulation of gene expression. The steady-state levels of O-GlcNAc are influenced by extracellular glucose concentrations suggesting that O-GlcNAcylation may serve as a metabolic
