Description:
The dynamic glycosylation of serine or threonine residues on nuclear and cytosolic proteins by O-linked beta-N-acetylglucosamine (O-GlcNAc) is abundant in all multicellular eukaryotes. On several proteins, O-GlcNAc and O-phosphate alternatively occupy the same or adjacent sites, leading to the hypothesis that one function of this saccharide is to transiently block phosphorylation. The diversity of proteins modified by O-GlcNAc implies its importance in many basic cellular and disease processes. Here we systematically examine the current data implicating O-GlcNAc as a regulatory modification important to signal transduction cascades.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wells, L -- Vosseller, K -- Hart, G W -- CA42486/CA/NCI NIH HHS/ -- CA83261/CA/NCI NIH HHS/ -- GM20528/GM/NIGMS NIH HHS/ -- HD13563/HD/NICHD NIH HHS/ -- New York, N.Y. -- Science. 2001 Mar 23;291(5512):2376-8.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Biological Chemistry, Johns Hopkins School of Medicine, 725 North Wolfe Street, Baltimore, MD 21205 USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/11269319" target="_blank"〉PubMed〈/a〉
