A chemical glycoproteomics platform reveals O-GlcNAcylation of mitochondrial voltage-dependent anion channel 2.
(Cell Rep, 2013-10-31)Protein modification by O-linked β-N-acetylglucosamine (O-GlcNAc) is a critical cell signaling modality, but identifying signal-specific O-GlcNAcylation events remains a significant experimental challenge. Here, we describe ... -
A novel inflammatory biomarker, GlycA, associates with disease activity in rheumatoid arthritis and cardio-metabolic risk in BMI-matched controls.
(Arthritis Res Ther, 2016-04-12)BACKGROUND: RA and CVD both have inflammation as part of the underlying biology. Our objective was to explore the relationships of GlycA, a measure of glycosylated acute phase proteins, with inflammation and cardiometabolic ... -
Dynamic Glycosylation Governs the Vertebrate COPII Protein Trafficking Pathway.
(Biochemistry, 2018-01)The COPII coat complex, which mediates secretory cargo trafficking from the endoplasmic reticulum, is a key control point for subcellular protein targeting. Because misdirected proteins cannot function, protein sorting by ... -
Glycosylation of KEAP1 links nutrient sensing to redox stress signaling.
(The EMBO journal, 2017-08)O-GlcNAcylation is an essential, nutrient-sensitive post-translational modification, but its biochemical and phenotypic effects remain incompletely understood. To address this question, we investigated the global transcriptional ... -
Metabolic cross-talk allows labeling of O-linked beta-N-acetylglucosamine-modified proteins via the N-acetylgalactosamine salvage pathway.
(Proceedings of the National Academy of Sciences of the United States of America, 2011-02-07)Hundreds of mammalian nuclear and cytoplasmic proteins are reversibly glycosylated by O-linked β-N-acetylglucosamine (O-GlcNAc) to regulate their function, localization, and stability. Despite its broad functional significance, ... -
NgBR is essential for endothelial cell glycosylation and vascular development.
(EMBO Rep, 2016-02)NgBR is a transmembrane protein identified as a Nogo-B-interacting protein and recently has been shown to be a subunit required for cis-prenyltransferase (cisPTase) activity. To investigate the integrated role of NgBR in ... -
Site-specific glycosylation regulates the form and function of the intermediate filament cytoskeleton.
(eLife, 2018-03-07)Intermediate filaments (IF) are a major component of the metazoan cytoskeleton and are essential for normal cell morphology, motility, and signal transduction. Dysregulation of IFs causes a wide range of human diseases, ... -
Structure of HIV-1 gp120 V1/V2 domain with broadly neutralizing antibody PG9.
(Nature, 2011-11-23)Variable regions 1 and 2 (V1/V2) of human immunodeficiency virus-1 (HIV-1) gp120 envelope glycoprotein are critical for viral evasion of antibody neutralization, and are themselves protected by extraordinary sequence diversity ... -
Suppressyn localization and dynamic expression patterns in primary human tissues support a physiologic role in human placentation.
(Scientific reports, 2019-12)We previously identified suppressyn (SUPYN), a placental protein that negatively regulates the cell fusion essential for trophoblast syncytialization via binding to the trophoblast receptor for syncytin-1, ASCT2, and hypothesized ... -
The structure of irisin reveals a novel intersubunit β-sheet fibronectin type III (FNIII) dimer: implications for receptor activation.
(The Journal of biological chemistry, 2013-11)Irisin was recently identified as a putative myokine that is induced by exercise. Studies suggest that it is produced by cleavage of the FNDC5 (fibronectin domain-containing protein 5) receptor; irisin corresponds to the ... -
Total synthesis of cyanolide A and confirmation of its absolute configuration.
(Org Lett, 2010-06-18)The tandem allylic oxidation/oxa-Michael reaction promoted by the gem-disubstituent effect and the 2-methyl-6-nitrobenzoic anhydride (MNBA)-mediated dimerization were explored for the efficient and facile synthesis of cyanolide ...
