Loss of heparan sulfate glycosaminoglycan assembly in podocytes does not lead to proteinuria.
Podocytes synthesize the majority of the glomerular basement membrane components with some contribution from the glomerular capillary endothelial cells. The anionic charge of heparan sulfate proteoglycans is conferred by covalently attached heparan sulfate glycosaminoglycans and these are thought to provide critical charge selectivity to the glomerular basement membrane for ultrafiltration. One key component in herparan sulfate glycosaminoglycan assembly is the Ext1 gene product encoding a subunit of heparan sulfate co-polymerase. Here we knocked out Ext1 gene expression in podocytes halting polymerization of heparin sulfate glycosaminoglycans on the proteoglycan core proteins secreted by podocytes. Glomerular development occurred normally in these knockout animals but ...http://repository.ubn.ru.nl/handle/2066/69069
The heparin/heparan sulfate sequence that interacts with cyclophilin B contains a 3-O-sulfated N-unsubstituted glucosamine...
Many of the biological functions of heparan sulfate (HS) proteoglycans can be attributed to specialized structures within HS moieties, which are thought to modulate binding and function of various effector proteins. Cyclophilin B (CyPB), which was initially identified as a cyclosporin A-binding protein, triggers migration and integrin-mediated adhesion of peripheral blood T lymphocytes by a mechanism dependent on interaction with cell surface HS. Here we determined the structural features of HS that are responsible for the specific binding of CyPB. In addition to the involvement of 2-O,6-O, and N-sulfate groups, we also demonstrated that binding of CyPB was dependent on the presence of N-unsubstituted glucosamine residues (GlcNH2), which have been reported to be precursors for sulfation by 3-O-sulfotransferases-3 (3-OST-3). Interestingly, 3-OST-3B isoform was found to be the main 3-OST isoenzyme expressed in peripheral blood ...http://christie.openrepository.com/christie/handle/10541/71358
國立交通大學機構典藏：Synthetic heparin and heparan sulfate oligosaccharides and their protein interactions
Heparin and heparan sulfate bind a host of basic proteins that take advantage of the sugar's dense structural information. The significance of these interactions in various aspects of development, physiology, and disease stimulated keen interest in evaluating structure-activity relationships. The well-defined heparin and heparan sulfate oligosaccharides needed for these studies can be mainly accessed by chemical synthesis and, more recently by chemoenzymatic means. The various synthetic strategies available to chemical synthesis have recently enabled the acquisition of several regular and irregular sequences, including a number of dodecasaccharides, through improved coupling methods and judicial protecting group manipulations. Controlled chain elongation and critical application of modification enzymes allowed the generation of well-defined constructs via chemoenzymatie ...https://ir.nctu.edu.tw/handle/11536/23654
Altered glycosylation of recombinant NKp30 hampers binding to heparan sulfate: a lesson for the use of recombinant...
NKp30 is a natural cytotoxicity receptor expressed by human NK cells and involved in NK lytic activity. We previously published that membranal heparan sulfate serves as a coligand for human NKp30. In the present study, we complement our results by showing direct binding of recombinant NKp30 to immobilized heparin. The heparan sulfate epitope(s) on target tumor cells and the heparin epitope(s) recognized by NKp30 share similar characteristics. Warren and colleagues (Warren HS, Jones AL, Freeman C, Bettadapura J, Parish CR. 2005.

Regulation of FGF-1 mitogenic activity by heparan sulfate oligosaccharides is dependent on specific structural features:...
The interaction of heparan sulfate (HS) (and the closely related molecule heparin) with FGF-1 is a requirement for enabling the growth factor to activate its cell surface tyrosine kinase receptor. However, little is known about the regulatory role of naturally occurring cell surface HS in FGF-1 activation. We have addressed this issue by utilizing a library of HS oligosaccharides, which are defined in both length and sulfate content. Mitogenic activation assays using these oligosaccharides showed that HS contained both FGF-1 activatory and inhibitory sugar sequences. Further analysis of these oligosaccharides showed a clear correlation between FGF-1 promoting activity and their 6-O-sulfate content. The results, in particular with the dodecasaccharide sequences, suggested that specific positioning of 6-O-sulfate groups may be required for the ...http://eprints.hud.ac.uk/id/eprint/2268/

A cyclic anti-heparan sulfate peptide provides protection against primary and recurrent herpes simplex virus-1 (HSV-1)...
Purpose : Primary and recurrent ocular herpes infections affect almost 60-90% of the population and in severe cases is one of the leading causes of infectious blindness. This study describes the topical use of a cyclic anti-heparan sulfate peptide that shows promise in blocking ocular herpes infections. Methods : Cyclic peptide synthesis and confirmation was performed at the Protein Research Laboratory at the University of Illinois at Chicago. A random cyclic peptide sequence was also generated to serve as a control. Cell viability assay via MTT was performed in human corneal epithelial cells (HCE) to rule out non-toxic concentrations. HSV-1 virus entry using a recombinant virus strain encoding the beta-galactosidase gene and viral protein synthesis and replication of HSV-1 were assayed in the presence of the control and treatment cyclic peptides. Using the mouse corneas as a model of ocular infection, the therapeutic activity of the cyclic peptide was ...http://iovs.arvojournals.org/article.aspx?articleid=2641397
"Basement membrane proteoglycans: modulators Par Excellence of cancer g" by Renato V. Iozzo, Jason J. Zoeller et al.
Proteoglycans located in basement membranes, the nanostructures underling epithelial and endothelial layers, are unique in several respects. They are usually large, elongated molecules with a collage of domains that share structural and functional homology with numerous extracellular matrix proteins, growth factors and surface receptors. They mainly carry heparan sulfate side chains and these contribute not only to storing and preserving the biological activity of various heparan sulfate-binding cytokines and growth factors, but also in presenting them in a more 'active configuration' to their cognate receptors. Abnormal expression or deregulated function of these proteoglycans affect cancer and angiogenesis, and are critical for the evolution of the tumor microenvironment. This review will focus on the functional roles of the major heparan sulfate ...http://jdc.jefferson.edu/pacbfp/26/

Heparan sulfate (HS), a linear negatively charged polysaccharide located at the cell surface and in the extracellular matrix, interacts with, and thereby regulates the functions of numerous proteins. HS-protein interactions depend on the fine structure of HS, especially its sulfation pattern. This thesis aimed to understand how differently sulfated domains in HS are generated. Specifically, the substrate specificities of HS hexuronic acid 2-O-sulfotransferase (2OST) and HS glucosaminyl 6-O-sulfotransferases (6OSTs) were investigated. Three different 6OSTs (6OST1-3) have been cloned and characterized. To study the mechanisms controlling 6-O-sulfation we incubated the recombinant purified 6-OST isoforms with different 6-O-desulfated poly- and oligosaccharide substrates and the active sulfate donor 3'-phosphoadenosine ...http://uu.diva-portal.org/smash/record.jsf?pid=diva2:165615

Heparan sulfate proteoglycans are critical for the organization of the extracellular distribution of Wingless | Development
Recent studies in Drosophila have shown that heparan sulfate proteoglycans (HSPGs) are required for Wingless (Wg/Wnt) signaling. In addition, genetic and phenotypic analyses have implicated the glypican gene dally in this process. Here, we report the identification of another Drosophila glypican gene, dally-like (dly) and show that it is also involved in Wg signaling. Inhibition of dly gene activity implicates a function for DLY in Wg reception and we show that overexpression of DLY leads to an accumulation of extracellular Wg. We propose that DLY plays a role in the extracellular distribution of Wg. Consistent with this model, a dramatic decrease of extracellular Wg was detected in clones of cells that are deficient in proper glycosaminoglycan biosynthesis. We conclude that HSPGs play an important role in organizing the extracellular distribution of Wg.. ...http://dev.biologists.org/content/128/1/87

KEGG PATHWAY: Glycosaminoglycan biosynthesis - heparan sulfate / heparin - Reference pathway + Vertebrates
Heparan sulfate (HS) and heparin (Hep) are glycosaminoglycans with repeating disaccharide units that consist of alternating residues of alpha-D-glucosamine (GlcN) and uronic acid, the latter being either beta-D-glucuronic acid (GlcA) or alpha-L-iduronic acid (IdoA). In these sugar residues, sulfation modification may be performed at various positions. Structural studies show that Hep possesses a higher degree of sulfation than HS. The biosynthesis of HS/Hep occurs with the addition of the first GlcNAc residue by EXTL3 glycosyltransferase after completion of tetrasaccharide linkage region attached to serine residue of a core protein. The chain polymeraization is then catalyzed by EXT1 and EXT2 transferases. As the chain polymerizes, HS/Hep undergoes a series of modification reactions including N-deacetylation, N-sulfation, epimerization, and subsequently O-sulfation. As final products of biosynthesis, HS is present in the form of hepran ...http://www.genome.jp/kegg-bin/show_pathway?category=Vertebrates&mapno=00534
Heparan sulfate 2-O-sulfotransferase 1
Heparan sulfate biosynthetic enzymes are key components in generating a myriad of distinct heparan sulfate fine structures that carry out multiple biologic activities. This gene encodes a member of the heparan sulfate biosynthetic enzyme family that transfers sulfate to the 2 position of the iduronic acid residue of heparan sulfate. The disruption of this gene resulted in no kidney formation in knockout embryonic mice, indicating that the absence of this enzyme may interfere with the signaling required for kidney formation. Two alternatively spliced transcript variants that encode different proteins have been found for this gene. [provided by RefSeq, Aug 2008 ...https://pharos.nih.gov/idg/targets/Q7LGA3

DSpace@MIT: Heparan sulfate glycosaminoglycan regulation of vasculogenesis
Neovascularization is an essential process to repair ischemic tissues following myocardial infarction, stroke, diabetic complications, or transplant procedures. Blood vessels are generated by distinct vasculogenic and angiogenic processes. Although multiple proangiogenic factors have been identified, limited success has been achieved translating these as clinical therapeutics. Furthermore, recent studies have shown that vasculogenesis contributes to adult neovascularization in multiple settings. Harnessing the vasculogenic potential of embryonic stem cells is an emerging concept to generate neovasculature. The differentiation of embryonic stem cells into endothelium has been well documented, however most studies focus on genetic or chemokine regulation. Limited information exists which implicates the role of the extracellular microenvironment in stem cell differentiation. Heparan sulfate glycosaminoglycans (HSGAG) are a crucial part of the dynamic ...http://dspace.mit.edu/handle/1721.1/63084
Endostatin is recognized by heparan sulfate epitopes containing both sulfated and acetylated N-substituents
Heparan sulfate (HS) is a polysaccharide of glycosaminoglycan type composed of alternating hexuronic acid [either glucuronic acid (GlcA) or iduronic acid (IdoA)] and glucosamine (GlcN) units that can be sulfated in various positions. HS binds to a large number of proteins and these interactions promote many biological processes, including cell adhesion and growth factor signaling. This thesis deals with the structural analysis of short heparan sulfate sequences that mediate binding to fibroblast growth factors FGF1 and FGF2, their receptor FGFR4, and the angiogenesis inhibitor endostatin.. Both FGF1 and FGF2 were shown to interact with N-sulfated hexa- and octasaccharide fragments isolated from HS. A pool of HS fragments depleted for FGF1 binding retained the ability to bind FGF2. Changes in 6-O sulfation affected binding to FGF1 but not ...http://uu.diva-portal.org/smash/record.jsf?pid=diva2:161078

Snapping Up Sulfate | Science
Sulfate-binding proteins hold their ligands by means of a large number of neutral hydrogen-bonding interactions, but designers of small synthetic receptors generally have had to resort to electrostatic interactions to capture the sulfate ion. Bondy et al. have modified a system for binding sulfate that relies on Pt2+ centers (which provide an electrostatic interaction) that sport four nicotinamide arms (which form hydrogen bonds). Now, by using iso-quinoline ligands derivatized with urea groups, they can stabilize sulfate binding in deuterated dimethyl sulfoxide (DMSO-d6) enough so that they can follow anion binding on the nuclear magnetic resonance time scale. Halides formed 2:1 complexes with these receptors, but the four urea moieties converged on a single sulfate ion in a 1:1 complex featuring eight hydrogen bonds, as revealed by x-ray ...http://science.sciencemag.org/content/304/5669/361.3
