Crystal structures of two H-2Db/glycopeptide complexes suggest a molecular basis for CTL cross-reactivity. (1/1610)

Two synthetic O-GlcNAc-bearing peptides that elicit H-2Db-restricted glycopeptide-specific cytotoxic T cells (CTL) have been shown to display nonreciprocal patterns of cross-reactivity. Here, we present the crystal structures of the H-2Db glycopeptide complexes to 2.85 A resolution or better. In both cases, the glycan is solvent exposed and available for direct recognition by the T cell receptor (TCR). We have modeled the complex formed between the MHC-glycopeptide complexes and their respective TCRs, showing that a single saccharide residue can be accommodated in the standard TCR-MHC geometry. The models also reveal a possible molecular basis for the observed cross-reactivity patterns of the CTL clones, which appear to be influenced by the length of the CDR3 loop and the nature of the immunizing ligand.  (+info)

Gangliosides of human kidney. (2/1610)

Five gangliosides isolated from human kidney have been characterized. The two main fractions were shown to be typical extraneural gangliosides in having lactose as their neutral carbohydrate moiety. Their structures were identified as: AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-8)AcNeu(alpha2-3)Gal(beta1-4)Glc(beta1-1)Cer. The two main hexosamine-containing gangliosides are structurally related to human blood group substances of glycosphingolipid nature. The following structures are postulated: AcNeu(alpha2-3)Gal(beta1-4)GlcNAc(beta1-3)Gal(beta1-4)Glc(beta1-1)Cer and AcNeu(alpha2-3)Gal(beta1-4)[Fuc(alpha1-3)]GlcNAc(beta1-3)Gal(beta1-4)Glc(beta1-1) Cer. The third hexosamine-containing ganglioside belongs to a different series of glycolipids and was shown to have the structure of a major ganglioside of human brain: AcNeu(alpha2-3)Gal(beta1-3)GalNAc(beta1-4)[AcNeu(alpha2-3)]Gal(beta1-4)Glc(beta1- 1)Cer. The fatty acid structure of different gangliosides was shown to resemble that of neutral glycolipids of human kidney with the nonhydroxy acids C16:0, C22:0, and C24:0 as major components.  (+info)

Participation of a trisaccharide-lipid in glycosylation of oviduct membrane glycoproteins. (3/1610)

Preincubation of a hen oviduct membrane preparation with UDP-Nactyl[14C]glucosamine and bacitracin, followed by incubation with GDP-mannose, leads to formation of a chloroform/methanol (2/1)-extractable glycolipid. Treatment of the lipid with mild acid results in the release of a trisaccharide shown to have the structure beta-mannosyl-N-acetylglucosamineyl-N-acetylglucosamine. Incubation of purified trisaccharide-lipid with oviduct membranes in the presence of sodium deoxycholate, Mn2+, and GDP-mannose leads to formation of a labeled glycoprotein with an apparent molecular weight of 25,000...  (+info)

Lectin receptor sites on rat liver cell nuclear membranes. (4/1610)

The presence and localization of lectin receptor sites on rat liver cell nuclear and other endomembranes was studied by light and electron microscopy using fluorescein and ferritin-coupled lectin conjugates. Isolated nuclei labelled with fluorescein-conjugated Concanavalin A (Con A) or wheat germ agglutinin (WGA) often showed membrane staining, which sometimes was especially bright on small stretches of the nuclear surface. Unlabelled nuclei and nuclei with a complete ring fluorescence were also seen. The nuclear fluorescence corresponded in intensity to that seen on the surface of isolated rat liver cells. Con A-ferritin particles were seldom detected on the cytoplasmic surface of the intact nuclear envelope. However, at places where the 2 leaflets of the envelope were widely separated or where the outer nuclear membrane was partly torn away, heavy labelling was seen on the cisternal surface of both the inner and outer nuclear membranes. Labelling with Con A-ferritin was also found on the cisternal side of rough endoplasmic reticulum present in the specimens. No labelling was seen on the cytoplasmic surface of mitochondrial outer membrane. The results demonstrate the presence of binding sites for Con A and WGA in nuclei and an asymmetric localization of these sites on the cisternal side of ribosome-carrying endomembranes in rat liver cells.  (+info)

Role of surface proteins in Vibrio cholerae attachment to chitin. (5/1610)

The role of surface proteins in Vibrio cholerae attachment to chitin particles in vitro was studied. Treatment of V. cholerae O1 ATCC 14034 and ATCC 14035 with pronase E reduced the attachment of bacteria to chitin particles by 57 to 77%. A statistically significant reduction was also observed when the attachment to chitin was evaluated in the presence of homologous Sarkosyl-insoluble membrane proteins (MPs) (67 to 84%), N-acetylglucosamine (GlcNAc) (62%), the sugar that makes up chitin, and wheat germ agglutinin (40 to 56%), a lectin that binds GlcNAc. The soluble oligomers N,N'-diacetylchitobiose or N,N', N"-triacetylchitotriose caused an inhibition of 14 to 23%. Sarkosyl-insoluble MPs able to bind chitin particles were isolated and visualized by sodium dodecyl sulfate-polyacrylamide gel electrophoresis; two of these peptides (molecular sizes, 36 and 53 kDa) specifically bind GlcNAc.  (+info)

Platelet high affinity low density lipoprotein binding and import of lipoprotein derived phospholipids. (6/1610)

The binding of low density lipoprotein (LDL) to the platelet cell membrane could facilitate the transfer of phospholipids from LDL to the platelets. A polyclonal antibody against the platelet glycoproteins IIb/IIIa inhibited the high affinity binding of 125I-LDL by up to 80%. The transfer of pyrene (py)-labeled sphingomyelin (SM), phosphatidylcholine and phosphatidylethanolamine from LDL to the platelets was unaffected by the antibody. The lectin wheat germ agglutinin (WGA) reduced the binding of 125I-LDL to the platelets by approximately 80%. In contrast, the lectin stimulated the transfer of SM from LDL into the platelets by about three-fold. WGA also specifically augmented the transfer of py-SM between lipid vesicles and the platelets, the stimulation being abolished in the presence of N-acetylglucosamine. Dextran sulfate (DS) increased the specific binding of 125I-LDL to the platelets by up to 2.8-fold. On the other hand, the import of LDL-derived py-phospholipids was unaffected by DS. Together, the results indicate that the phospholipid transfer from LDL to the platelets is independent of the high affinity LDL binding to the platelets and is specifically stimulated by WGA. Thus, the interactions of platelets with LDL phospholipids differ markedly from those with the apoprotein components of the lipoproteins.  (+info)

Mutations that confer resistance to 2-deoxyglucose reduce the specific activity of hexokinase from Myxococcus xanthus. (7/1610)

The glucose analog 2-deoxyglucose (2dGlc) inhibits the growth and multicellular development of Myxococcus xanthus. Mutants of M. xanthus resistant to 2dGlc, designated hex mutants, arise at a low spontaneous frequency. Expression of the Escherichia coli glk (glucokinase) gene in M. xanthus hex mutants restores 2dGlc sensitivity, suggesting that these mutants arise upon the loss of a soluble hexokinase function that phosphorylates 2dGlc to form the toxic intermediate, 2-deoxyglucose-6-phosphate. Enzyme assays of M. xanthus extracts reveal a soluble hexokinase (ATP:D-hexose-6-phosphotransferase; EC 2.7.1.1) activity but no phosphotransferase system activities. The hex mutants have lower levels of hexokinase activities than the wild type, and the levels of hexokinase activity exhibited by the hex mutants are inversely correlated with the ability of 2dGlc to inhibit their growth and sporulation. Both 2dGlc and N-acetylglucosamine act as inhibitors of glucose turnover by the M. xanthus hexokinase in vitro, consistent with the finding that glucose and N-acetylglucosamine can antagonize the toxic effects of 2dGlc in vivo.  (+info)

Quantitative determination of N-acetylglucosamine residues at the non-reducing ends of peptidoglycan chains by enzymic attachment of [14C]-D-galactose. (8/1610)

The ability of human milk galactosyltransferase to attach D-galactose residues quantitatively to the C-4 of N-acetylglucosamine moieties at the ends of oligosaccharides has been utilized for the specific labeling and quantitative determination of the chain length of the glycan moiety of the bacterial cell wall. The average polysaccharide chain length of the soluble, uncrosslinked peptidoglycan secreted by Micrococcus luteus cells on incubation with penicillin G was studied with this technique and found to be approximately 70 hexosamines long. Furthermore, the peptidoglycan chain length of Escherichia coli sacculi of different cell shapes and dimensions was determined both in rod-shaped cells and in filaments induced by temperature shift of a division mutant or by addition of cephalexin or nalidixic acid. The average chain length found in most of these sacculi was between 70 and 100 hexosamines long. Small spherical 'mini' cells had chain lengths similar to those of the isogenic rod-like cells.  (+info)

O-linked â-N-acetylglucosamine is a regulatory post translational modification. This modification occurs on nearly all functional classes of proteins, in the nucleus and cytoplasm. O-GlcNAc is added to serine or threonine by O-GlcNAc transferase and removed by O-GlcNAcase. Previous attempts to study O-GlcNAc-modified proteins have resulted in low yields, making 3-dimensional structure determination impossible. In this dissertation O-GlcNAc transferase will be co-expressed with domains of human cAMP responsive element-binding protein (CREB1) and Abelson tyrosine-kinase 2 (ABL2) in E. coli, to produce O-GlcNAc-modified protein. The O-GlcNAc-modified protein was expressed in a variety of E. coli cell lines at a variety of conditions, but only small quantities of insoluble protein were produced. A glycosidase was suspected due to the disappearance of the O-GlcNAc modification from the protein. O-(2-acetamido-2-dexoy-dglucopyranosylidene) amino-N-phenylcarbamate (PUGNAc), a â-N-acetylglucosaminidase
O-GlcNAc1 is a dynamically regulated post-translational modification (PTM), in which a β-N-acetylglucosamine moiety is attached to hydroxyl side chains of serine or threonine residues of proteins by O-GlcNAc-transferase (1) and removed by β-N-acetylglucosaminidase (O-GlcNAcase) (2). O-GlcNAc is ubiquitous on nuclear and cytoplasmic proteins in all multicellular eukaryotes (3). Dynamic O-GlcNAcylation plays critical roles in signal transduction (4), transcriptional control (5, 6), cell cycle regulation (7), protein degradation (8), neurodegeneration (9), and stress responses (10). Abnormally regulated O-GlcNAcylation has been found in diseases such as diabetes (11) and Alzheimer disease (12).. The role of O-GlcNAcylation in signal transduction is at least in part related to its competitive interplay with O-phosphorylation. Some of the known O-GlcNAc sites are the same as or adjacent to phosphorylation sites. For example, O-GlcNAc is reciprocal to O-phosphorylation on the C-terminal domain of ...

N2 - Many phosphorylation signal transduction pathways in the eukaryotic cell are modulated by posttranslational modification of specific serines/threonines with N-acetylglucosamine (O-GlcNAc). Levels of O-GlcNAc on key proteins regulate biological processes as diverse as the cell cycle, insulin signaling, and protein degradation. The two enzymes involved in this dynamic and abundant modification are the O-GlcNAc transferase and O-GlcNAcase. Structural data have recently revealed that the O-GlcNAcase possesses an active site with significant structural similarity to that of the human lysosomal hexosaminidases HexA/HexB. PUGNAc, an O-GlcNAcase inhibitor widely used to raise levels ...
The hexosamine biosynthetic pathway (HBP) generates the substrate for the O-linked β-N-acetylglucosamine (O-GlcNAc) modification of proteins. The HBP also serves as a stress sensor and has been reported to be involved with nuclear factor of activated T-cells (NFAT) activation, which can contribute to multiple cellular processes including cell metabolism, proliferation, and inflammation. In our previously published report, Fibroblast Growth Factor (FGF) 23, an important endocrine pro-inflammatory mediator, was shown to activate the FGFR4/phospholipase Cγ (PLCγ)/nuclear factor of activated T-cells (NFAT) signaling in chronic inflammatory airway diseases such as cystic fibrosis (CF) and chronic obstructive pulmonary disease (COPD). Here, we demonstrate that FGF23 increased the O-GlcNAc modification of proteins in HBECs. Furthermore, the increase in O-GlcNAc levels by FGF23 stimulation resulted in the downstream activation of NFAT and secretion of interleukin-6 (IL-6). Conversely, inhibition of FGF23
Abstract: O-GlcNAc transferase (OGT) glycosylates a diverse range of intracellular proteins with O-linked N-acetylglucosamine (O-GlcNAc), an essential and dynamic post-translational modification in metazoans. Although this enzyme modifies hundreds of proteins with O-GlcNAc, it is not understood how OGT achieves substrate specificity. In this study, we describe the application of a high-throughput OGT assay to a library of peptides. We mapped sites of O-GlcNAc modification by electron transfer dissociation MS and found that they correlate with previously detected O-GlcNAc sites. Crystal structures of four acceptor peptides in complex with Homo sapiens OGT suggest that a combination of size and conformational restriction defines sequence specificity in the −3 to +2 subsites. This work reveals that although the N-terminal TPR repeats of OGT may have roles in substrate recognition, the sequence restriction imposed by the peptide-binding site makes a substantial contribution to O-GlcNAc site ...
Glycosylation is essential for growth factor signaling through N-glycosylation of ligands and receptors and the biosynthesis of proteoglycans as co-receptors. Here, we show that protein O-GlcNAcylation is crucial for fibroblast growth factor (FGF) signaling in Drosophila. We found that nesthocker (nst) encodes a phosphoacetylglucosamine mutase and that nst mutant embryos exhibited low amounts of intracellular uridine 5′-diphosphate-N-acetylglucosamine (UDP-GlcNAc), which disrupted protein O-GlcNAcylation. Nst was required for mitogen-activated protein kinase (MAPK) signaling downstream of FGF but not MAPK signaling activated by epidermal growth factor. nst was dispensable for the function of the FGF ligands and the FGF receptors extracellular domain but was essential in the signal-receiving cells downstream of the FGF receptor. We identified the adaptor protein Downstream of FGF receptor (Dof), which interacts with the FGF receptor, as the relevant target for O-GlcNAcylation in the FGF ...

Methods. O-GlcNAcylated proteins were identified by two-dimensional gel electrophoresis, immunoblotting and peptide mass fingerprinting.

Introduction: Aortic valve (AV) disease is a significant contributor to cardiovascular mortality. AV calcification occurs preferentially on the fibrosa side, where endothelial cells (ECs) are subjected to characteristic oscillatory shear stress (OS), whereas the ventricularis ECs experience stable unidirectional laminar shear stress (LS). OS and LS differently regulate endothelial function via gene expression and protein modification. While the post-translational β-N-acetylglucosamine modification of amino acids (O-GlcNAcylation) has been shown to be important in the function of various cell types, its role in AV disease is unknown. We hypothesized that OS impairs EC O-GlcNAcylation, leading to AV inflammation and calcification.. Methods and Results: Immunostaining analysis showed that O-GlcNAcylation was decreased in fibrosa endothelium compared to ventricularis in human and porcine AVs, and human AV ECs (HAVECs) exhibited increased O-GlcNAcylation by LS (20 dyn/cm2) and decreased by OS (+5 ...
In order for a protein modification to play an active role in signal transduction, it needs to have certain key features. First, the modification needs to be dynamic. For the proteins that have been examined to date, the O-GlcNAc half-life is much shorter than that of the modified polypeptide chain (8). Second, the removal or attachment of the modification should be inducible by certain stimuli. O-GlcNAc modification of certain proteins is known to change in response to T cell activation, insulin signaling, glucose metabolism, and cell cycle progression (6). Thus, O-GlcNAc displays features essential for a role in signal transduction.. Consistent with O-GlcNAc being dynamic and inducible, regulated nucleocytoplasmic enzymes for the attachment [O-GlcNAc transferase (OGT)] and for the removal (O-GlcNAcase) of the modification have been purified, characterized, and cloned (9-12). The OGT enzyme is modified by both O-GlcNAc and tyrosine phosphorylation and has 11 protein-protein interaction domains ...
The O-GlcNAc (O-linked N-acetylglucosamine) modification is a dynamic and reversible form of protein glycosylation occurring on specific serine and threonine residues of intracellular proteins [1,2]. Since the initial discovery of O-GlcNAc [3], technological advances have greatly facilitated its detection, and proteomics studies [4-6] have shown that a significant proportion of cellular proteins are O-GlcNAcylated. However, the functional importance of O-GlcNAc is only just emerging, with evidence to suggest that it may regulate protein activity in a manner analogous (and complementary) to phosphorylation [7]. O-GlcNAc levels are known to respond dynamically to nutrient availability [1] and stress [8], and to undergo changes during the cell cycle [9] and development [10]. O-GlcNAc has been shown to be associated with a range of human diseases [2]. Strikingly, only two enzymes orchestrate the O-GlcNAc modification. Both the OGT (O-GlcNAc transferase) and its antagonistic OGA (O-GlcNAcase or ...

N2 - Regulatory T (Treg) cells control self-tolerance, inflammatory responses and tissue homeostasis. In mature Treg cells, continued expression of FOXP3 maintains lineage identity, while T cell receptor (TCR) signaling and interleukin-2 (IL-2)/STAT5 activation support the suppressive effector function of Treg cells, but how these regulators synergize to control Treg cell homeostasis and function remains unclear. Here we show that TCR-activated posttranslational modification by O-linked N-Acetylglucosamine (O-GlcNAc) stabilizes FOXP3 and activates STAT5, thus integrating these critical signaling pathways. ...
Several lectins recognize n-acetyl-glucosamine in a glycoprotein. Based on the linkage and specificity for binding, different N-Acetyl-Glucosamine-binding lectins are utilized to obtain optimum results.
This gene encodes a glycosyltransferase that catalyzes the addition of a single N-acetylglucosamine in O-glycosidic linkage to serine or threonine residues. Since both phosphorylation and glycosylation compete for similar serine or threonine residues, the two processes may compete for sites, or they may alter the substrate specificity of nearby sites by steric or electrostatic effects. The protein contains multiple tetratricopeptide repeats that are required for optimal recognition of substrates. Alternatively spliced transcript variants encoding distinct isoforms have been found for this gene. [provided by RefSeq, Oct 2009 ...

Nutrients regulate gene transcription by the dynamic cycling of O-linked N-acetylglucosamine (O-GlcNAc) on proteins that constitute the transcriptional machinery. A study shows that O-GlcNAcylation of the nuclear factor κB (NF-κB) subunit c-Rel is required for its binding to the promoters of some, but not all, key T cell receptor-dependent genes; however, O-GlcNAcylation is dispensable for the binding of c-Rel to the promoters of tumor necrosis factor-α-dependent genes. This study not only illustrates how specific stimuli that act on the same transcription factor can elicit the expression of particular sets of genes, it also suggests a possible mechanism for autoimmunity in diabetes.. ...
Protein glycosylation is usually relegated to the cell surface and intracellular compartments. In a fascinating exception to this rule that was first observed in the 1980s, A GlcNAc monosaccharide can be added to serine and threonine residues of cytosolic proteins. Many labs are trying to understand the dynamic regulation of the addition and removal of this sugar that seemingly has a hand in every cellular process and disease state known to man. More and more examples are being found to suggest that this modification and phosphorylation regulate each other, as if they werent already complicated enough on their own.. There are a handful of ways to detect O-GlcNAc, which have helped build the laundry list by telling us which proteins are modified. Now, in a recent Nature Chemical Biology paper from Linda Hsieh-Wilsons lab at CalTech, they show us a useful new method that reveals what proportion of any particular protein is modified (2%? 80%), and of those that are modified, exactly how many ...

Cancer cells increase nutrient consumption leading to the altered metabolic state known as the Warburg effect. One pathway dependent on glucose, glutamine and acetyl-CoA is the Hexosamine Biosynthetic Pathway (HBP). Increased flux through the HBP leads to elevated post-translation addition of O-linked-β-N-acetylglucosamine (O-GlcNAc) on a diverse population of nuclear and cytosolic proteins, many of which are implicated in cancer. Recently, our lab provided the first evidence that breast and prostate cancers increases total O-GlcNAcylation by increasing O-GlcNAc Transferase (OGT) levels. Importantly, reducing OGT activity inhibits cancer cell invasion in vitro and metastasis in vivo. OGT inhibition reduces breast and prostate cancer cell invasion through, in part, inhibition of the oncogenic transcription factor, FOXM1 and its transcriptional target matrix metalloproteinase 2 (MMP2). Here, we show that OGT regulation of FOXM1 and cancer cell invasion requires regulation of the NAD+-dependent ...

Comparison of the staining intensity in neurons expressing dsRED alone (= 23) to that in nontransfected neurons from cultures transfected with either dsRED (= 23) or dsRED + O-GlcNAcase (= 25) did not reveal a difference (> 0.32 and > 0.21 respectively, 2-tailed Welch > 0.25, 2-tailed Welch = 23) to dsRED transfected neurons revealed a 61% decrease in O-GlcNAc staining intensity (< 0.00001, 2-tailed Welch = 140) of O-GlcNAcase over-expressing neurons exhibited one LY310762 supplier or more branches relative to 20% (= 60) of dsRED alone expressing control neurons [Fig. 2(E)].

How protein structure is established is a fascinating question and a field that is actively studied by prominent labs around the world. Protein folding is the process of a chain of amino acids curling into its final shape, and how this process occurs is complex and not completely understood. In general proteins fold depending on their environment (exposed to water or not, for example) and with the help of other proteins, called chaperones. Protein chaperones help to establish a proteins structure as well as maintain it during times of stress. Further, modifications on proteins can change their structures, such as when p53, a protein that is involved in regulating many processes within the cell, is phosphorylated - its structure and, consequently, its function is altered slightly ...

Hyperglycemia, a hallmark of diabetes mellitus, is associated with increased vascular calcification and increased modification of proteins by O-linked N-acetylglucosamine (O-GlcNAcylation). OBJECTIVE:: We sought to determine the role of protein O-GlcNAcylation in regulating vascular calcification and the underlying mechanisms. METHODS AND RESULTS:: Low-dose streptozotocin-induced diabetic mice exhibited increased aortic ...

The cardioprotective capacity and the influence on myocardial O-GlcNAc levels of plasma dialysate from eight healthy volunteers and eight type 2 diabetic patients drawn before and after subjection to an rIPC stimulus were tested on human isolated atrial trabeculae subjected to ischaemia/reperfusion injury. Dialysate from healthy volunteers exposed to rIPC improved post-ischaemic haemodynamic recovery (40 ± 6 vs. 16 ± 2%; P , 0.01) and increased myocardial O-GlcNAc levels. Similar observations were made with dialysate from diabetic patients before exposure to rIPC (43 ± 3 vs. 16 ± 2%; P , 0.001) but no additional cardioprotection or further increase in O-GlcNAc levels was achieved by perfusion with dialysate after exposure to rIPC (44 ± 4 and 42 ± 5 vs. 43 ± 3%; P = 0.7). The glutamine:fructose-6-phosphate amidotransferase (GFAT) inhibitor azaserine abolished the cardioprotective effects and the increment in myocardial O-GlcNAc levels afforded by plasma from diabetic patients and healthy ...

AU - Barkovskaya, Anna. AU - Bathen, Tone F. AU - Moestue, Siver A. AU - Mills, Ian G. PY - 2016/1/27. Y1 - 2016/1/27. N2 - Metabolic networks are highly connected and complex, but a single enzyme, O-GlcNAc transferase (OGT) can sense the availability of metabolites and also modify target proteins. We show that inhibition of OGT activity inhibits the proliferation of prostate cancer cells, leads to sustained loss of c-MYC and suppresses the expression of CDK1, elevated expression of which predicts prostate cancer recurrence (p=0.00179). Metabolic profiling revealed decreased glucose consumption and lactate production after OGT inhibition. This decreased glycolytic activity specifically sensitized prostate cancer cells, but not cells representing normal prostate epithelium, to inhibitors of oxidative ...
Cardiosurgery is mostly done under cardiopulmonary bypass. However, the cardiopulmonary bypass and the later recovery of spontaneous circulation, a cardiac ischemia / reperfusion process, may cause myocardial damage and affect cardiac function as well as prognosis.. Glutamine, an amino acid abundant in the human body, plays an important role in the regulation of metabolism and immune cells and the protection of organs. Relative lack of glutamine is reported during stress or serious illness. Animal studies have confirmed that pretreatment with glutamine has a protective effect on the heart, liver, kidney and other organs post ischemia / reperfusion injury. It is also established that glutamine exerts myocardial protection mainly by activating hexosamine biosynthetic pathway, increasing intracellular O-GlcNAc protein modification and expression of heat shock protein 70 (HSP70), starting the protective reaction in the body, improving the function of myocardial cells, and inhibiting the release of ...
Pomgnt1 (untagged) - Mouse protein O-linked mannose beta1,2-N-acetylglucosaminyltransferase (Pomgnt1), transcript variant 1, (10ug), 10 µg.
SUMMARY: The enzymes of N-acetyl-D-glucosamine (GlcNAc) metabolism, GlcNAc-6-phosphate deacetylase and GlcN-6-phosphate deaminase were found to be inducible in Candida albicans. The pattern of induction for these enzymes was the same under conditions of germ-tube formation (37 °C) and where yeast cells metabolized GlcNAc with no change in morphology (28 °C); this indicates that these enzymes are not control points in the dimorphic development of C. albicans. During induction there was a 40- and 25-fold increase in specific activity for the deacetylase and the deaminase, respectively, and the maximum specific activity corresponded to the time when all the GlcNAc had been metabolized. The presence of lomofungin (an inhibitor of transcription) or trichodermin (an inhibitor of translation) in cell suspensions of C. albicans containing GlcNAc prevented the increase in specific activity of these enzymes. 2-Deoxyglucose inhibited germ-tube formation, partially inhibited the induction of the deacetylase (43%)
TY - JOUR. T1 - Analysis of nucleocytoplasmic protein shuttling by imaging flow cytometry. AU - Fasler-Kan, Elizaveta. AU - Baiken, Yeldar. AU - Vorobjev, Ivan A.. AU - Barteneva, Natasha S.. PY - 2016. Y1 - 2016. N2 - Many intracellular signal transduction events involve the reversible shuttling of proteins between the cytoplasm and the nucleus. Study of these processes requires imaging information on the protein localization in a given cell and a large number of measurements to obtain sufficient statistics on the protein localization in the whole population. The protocol describes method for quantitative imaging flow cytometry analysis of intracellular distribution of NF-kappaB in ARPE-19 cells stained with specific fluorochrome-conjugated antibodies. The described technique alone or in combination with standard flow cytometry methods can be applied to study any protein undergoing translocation from cytoplasm into the nucleus in a variety of cell lines as well as in heterogeneous primary cell ...

This gene encodes an enzyme that acts in the lumen of the endoplasmic reticulum to catalyze the transfer of N-acetylglucosamine to serine or threonine residues of extracellular-targeted proteins. This enzyme modifies proteins containing eukaryotic growth factor (EGF)-like domains, including the Notch receptor, thereby regulating developmental signalling. Mutations in this gene have been observed in individuals with Adams-Oliver syndrome 4. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2015 ...
We have previously reported the substrate specificity of the cytosolic α-D-mannosidase purified from rat liver using Man9GlcNAc, i.e. Manα1-2Manα1-3(Manα1-2Manα1-6)Man α1-6(Manα1-2Manα1-2Manα1-3)Manβ1-4GlcNAc, as substrate [Grard, Saint-Pol, Haeuw, Alonso, Wieruszeski, Strecker and Michalski (1994) Eur. J. Biochem. 223, 99-106]. Man9GlcNAc is hydrolysed giving Man5GlcNAc, i.e. Manα1-2Manα1-2Manα1-3(Manα1-6)Manβ1-4GlcNAc, possessing the same structure as the oligosaccharide of the dolichol pathway formed in the cytosolic compartment during the biosynthesis of N-glycosylprotein glycans. We study here the activity of the purified cytosolic α-D-mannosidase towards the oligosaccharide-diphosphodolichol intermediates formed during the biosynthesis of N-glycans, and also towards soluble oligosaccharides released from the endoplasmic reticulum which are glucosylated or not and possessing at their reducing end either a single N-acetylglucosamine residue or a di-N-acetylchitobiose ...
The protooncogene C-Myc (Myc) regulates cardiac hypertrophy. Myc promotes compensated cardiac function, suggesting that the operative mechanisms differ from those leading to heart failure. Myc regulation of substrate metabolism is a reasonable target, as Myc alters metabolism in other tissues. We hypothesize that Myc-induced shifts in substrate utilization signal and promote compensated hypertrophy. We used cardiac specific Myc-inducible C57/BL6 male mice between 4-6 months old that develop hypertrophy with tamoxifen (tam). Isolated working hearts and 13Carbon (13C )-NMR were used to measure function and fractional contributions (Fc) to the citric acid cycle by using perfusate containing 13C-labeled free fatty acids,more » acetoacetate, lactate, unlabeled glucose and insulin. Studies were performed at pre-hypertrophy (3-days tam, 3dMyc), established hypertrophy (7-days tam, 7dMyc) or vehicle control (cont). Non-transgenic siblings (NTG) received 7-days tam or vehicle to assess drug effect. ...

Full Text - Acyl-CoA ligase 4 (ACSL4) has been reported to be overexpressed in hepatocellular carcinoma (HCC) and to enhance cell proliferation. However, the molecular mechanisms underlying the role of ACSL4 in HCC progression remain largely unclear. Here, we aimed to investigate whether and how O-GlcNAcylation and ACSL4 regulate each other and HCC progression. The clinical significance of ACSL4, O-GlcNAc and GLUT1 in HCC was determined by Pearson chi-squared test and Kaplan-Meier analysis. CCK-8, flow cytometry and in vivo tumour formation assays were performed to detect cell proliferation, apoptosis and tumorigenesis. IP technology was used to evaluate the relationship between ACSL4 and O-GlcNAc. ACSL4, GLUT1 and O-GlcNAc levels were elevated in HCC tissues and predicted poor prognosis in HCC patients. ACSL4 overexpression significantly promoted cell proliferation and tumorigenesis and inhibited cell apoptosis, whereas these effects were all obviously impaired when mTOR signalling was repressed
Type 2 diabetes mellitus (T2DM) is a well-recognized independent risk factor for heart failure (HF). T2DM is associated with altered cardiac energy metabolism, leading to ectopic lipid accumulation and glucose overload, the exact contribution of these two parameters remaining unclear. To provide new insight into the mechanism driving the development of diabetic cardiomyopathy, we studied a unique model of T2DM: lipodystrophic Bscl2-/- (seipin knockout (SKO)) mice. Echocardiography and cardiac magnetic resonance imaging revealed hypertrophic cardiomyopathy with left ventricular dysfunction in SKO mice and these two abnormalities were strongly correlated with hyperglycemia. Surprisingly, neither intramyocardial lipid accumulation nor lipotoxic hallmarks were detected in SKO mice. 18F-FDG positron emission tomography showed increased myocardial glucose uptake. Consistently, the O-GlcNAcylated protein levels were markedly increased in SKO heart, suggesting a glucose overload. To test this ...
Certainly, N-acetylglucosamine appeared to accelerate the facilitated glucose uptake and boost each GAG and HA synthesis, suggesting that N-acetyl-glucosamine may perhaps be more efficient than native glucosamine. The American College of Rheumatology 2012 recommendations do not propose the use of glucosamine or chondroitin for the management of osteoarthritis. If there is advantage in terms of discomfort or function, it may well be continued. Sufferers nevertheless need to develop a comprehensive program with their physicians to treat osteoarthritis, which consists of diet plan, exercise, weight loss, and working with common, established drugs.. It is significant to point out that these research had been performed in various culture systems, with a variety of formulations and concentrations of glucosamine. The specifics of the culture systems and the formulations are provided in Table 2. Additionally, some of these studies compared the effects of two formulations of glucosamine in order to ...

A new technique for detecting proteins modified by β-N-acetyl-D-glucosamine (i.e., O-GlcNAc glycosylation) reveals that the process is reversible and dynamic in neurons and may even play a role in memory. Linda Hsieh-Wilson, California Institute of Technology, Pasadena, and colleagues have developed a quantitative isotopic and chemoenzymatic tagging system (QUIC-Tag) to detect glycosylated proteins inside neurons. Unlike some other methodologies, QUIC-Tag does not require metabolic incorporation of isotopes or rounds of cell division. Cellular levels of O-GlcNAc-proteins are also unperturbed. The technique, which involves protection of the O-GlcNAc moieties by biotinylation followed by avidin-based purification and then mass spectrometry detection, is particularly suited to non-dividing cells, such as neurons.. The technique is explained in detail in the May 13 Nature Chemical Biology online. First author Nelly Khidekel and colleagues also describe how they used the QUIC-Tag method to detect ...

Wheat germ agglutinin (WGA) is one of the most widely used lectins in cell biology. The receptor sugar for WGA is N-acetylglucosamine, with preferential binding to dimers and trimers of this sugar. WGA can bind oligosaccharides containing terminal N-acetylglucosamine or chitobiose, structures which are common to many serum and membrane glycoproteins. Bacterial cell wall peptidoglycans, chitin, cartilage glycosaminoglycans, and glycolipids can also bind WGA. Native WGA has also been reported to interact with some glycoproteins via sialic acid residues (see succinylated WGA). ...

In 2014, Gerald Hart, an associate editor for the Journal of Biological Chemistry, organized a thematic minireview series on O-GlcNAcylation. O-GlcNAc is found on many different proteins throughout the cell. Its function varies dependent upon the protein to which it is attached. Much like phosphorylation, one known purpose of O-GlcNAc is to control signaling in response to nutrients. Holt, who is now the chief science officer at NorthShore Bio, describes O-GlcNAc as an orthogonal method of regulating the same proteins: Its like a rivet: If theres a carbohydrate at a phosphorylation site, then that phosphorylation site is no longer regulated by classical phosphorylation pathways. Instead, it becomes regulated by the O-GlcNAc regulatory pathways.. Methods for studying phosphorylation have advanced rapidly in recent years, thanks in part to the existence of site-specific antibodies, while methods for studying O-GlcNAc continue to lag behind. Researchers only recently have begun to recognize the ...
