O-GlcNAc cycling: implications for neurodegenerative disorders Lazarus BD; Love DC; Hanover JAInt J Biochem Cell Biol 2009[Nov]; 41 (11): 2134-46The dynamic post-translational modification of proteins by O-linked N-acetylglucosamine (O-GlcNAc), termed O-GlcNAcylation, is an important mechanism for modulating cellular signaling pathways. O-GlcNAcylation impacts transcription, translation, organelle trafficking, proteasomal degradation and apoptosis. O-GlcNAcylation has been implicated in the etiology of several human diseases including type-2 diabetes and neurodegeneration. This review describes the pair of enzymes responsible for the cycling of this post-translational modification: O-GlcNAc transferase (OGT) and beta-N-acetylglucosaminidase (OGA), with a focus on the function of their structural domains. We will also highlight the important processes and substrates regulated by these enzymes, with an emphasis on the role of O-GlcNAc as a nutrient sensor impacting insulin signaling and the cellular stress response. Finally, we will focus attention on the many ways by which O-GlcNAc cycling may affect the cellular machinery in the neuroendocrine and central nervous systems.|Acetylglucosamine/*metabolism[MESH]|Acetylglucosaminidase/chemistry/metabolism[MESH]|Animals[MESH]|Gene Expression Regulation[MESH]|Glycosylation[MESH]|Humans[MESH]|N-Acetylglucosaminyltransferases/chemistry/metabolism[MESH]|Neurodegenerative Diseases/enzymology/genetics/*metabolism[MESH] |
