Abstract
O-linked N-acetylglucosamine (O-GlcNAc), a monosaccharide N-acetylglucosamine on the serine and threonine residues of nucleocytoplasmic proteins, is a novel protein modification that is ubiquitous among eukaryotes and implicated in cell regulation. Recent evidence indicates that O-GlcNAc regulates protein-protein interactions. Here we provide evidence that O-GlcNAc interrupts a known interaction between Sp1 and sterol regulatory element binding protein 2 (SREBP2), thereby inhibiting expression of the gene encoding acetyl-CoA synthetase 1, which is involved in lipid synthesis. This study suggests a novel mechanism in which lipid biosynthesis may be regulated by O-GlcNAc.
