HS, occurring about 1/20 disaccharides in heparin and less than 1/100 disaccharides in HS or not at all. The engagement of these receptors occurs outside the cell via a defined peptide segment in syndecan-1, but the activation mechanism is cytoplasmic and occurs via a talin-dependent, inside-out signaling pathway that requires syndecan-1 clustering. To address how HSPGs might regulate stem cells in their native cellular environments, Nakato and colleagues examined whether glypican participated in the maintenance of stem cells in the germline stem cell niche.

Syndecan-4 protects against osteopontin-mediated acute hepatic injury by masking functional domains of osteopontin Ectodermal syndecan-2 mediates left-right axis formation in migrating mesoderm as a cell-nonautonomous Vg1 cofactor Heparan sulfate is required for embryonic stem cells to exit from self-renewal Sequence analysis of heparan sulfate epitopes with graded affinities for fibroblast growth factors 1 and 2 Opposing activities of Dally-like glypican at high and low levels of Wingless morphogen activity Ksiazek I, Burkhardt C, Lin S, Seddik R, Maj M, Bezakova G, Jucker M, Arber S, Caroni P, Sanes JR, et al. Loss of glypican-3 function causes growth factor-dependent defects in cardiac and coronary vascular development Perlecan, the major proteoglycan of basement membranes, is altered in patients with Schwartz-Jampel syndrome (chondrodystrophic myotonia) Niemann CU, Abrink M, Pejler G, Fischer RL, Christensen EI, Knight SD, Borregaard N 2007. The HS chains of syndecan-4 bind to fibronectin, which together with integrin, induce formation of focal adhesions and stress fibers ( ) Fibroblasts attach and spread through [alpha]5[beta]1 integrin on coverslips coated with the integrin-binding domain of fibronectin but they do not form focal adhesions.

HSPGs can act as receptors for proteases and protease inhibitors regulating their spatial distribution and activity. Membrane proteoglycans cooperate with integrins and other cell adhesion receptors to facilitate cell-ECM attachment, cell-cell interactions, and cell motility. One class of these sites interacts with glycoprotein gD of Herpes simplex virus-1 and appears to be required for infection ( -sulfation, but the study of heparin-antithrombin interaction set the stage conceptually for searching for specific arrangements of sulfated sugars to achieve selective binding. Polycystic disease caused by deficiency in xylosyltransferase 2, an initiating enzyme of glycosaminoglycan biosynthesis Cornelison DDW, Wilcox-Adelman SA, Goetinck PF, Rauvala H, Rapraeger AC, Olwin BB 2004.

    If your computer's clock shows a date before 1 Jan 1970, the browser will automatically forget the cookie. The shedding of syndecan-4 and syndecan-1 from HeLa cells and human primary macrophages is accelerated by SDF-1/CXCL12 and mediated by the matrix metalloproteinase-9 Renal agenesis in mice homozygous for a gene trap mutation in the gene encoding heparan sulfate 2-sulfotransferase Campos-Xavier AB, Martinet D, Bateman J, Belluoccio D, Rowley L, Tan TY, Baxova A, Gustavson KH, Borochowitz ZU, Innes AM, et al.

    Generating this arrangement would presumably require spatial control over the assembly process, but how this is achieved in vivo is not known ( Docking of HS to chemokines. Syndecan-4 deficiency leads to high mortality of lipopolysaccharide-injected mice Izumikawa T, Kanagawa N, Watamoto Y, Okada M, Saeki M, Sakano M, Sugahara K, Sugihara K, Asano M, Kitagawa H 2010. Syndecan-1 may play a direct role in sealing the gaps between intestinal epithelial cells, acting as a physical barrier to prevent protein leakage ( ).

    Guanidinylated neomycin mediates heparan sulfate-dependent transport of active enzymes to lysosomes Glycomics approach to structure-function relationships of glycosaminoglycans Sasse P, Malan D, Fleischmann M, Roell W, Gustafsson E, Bostani T, Fan Y, Kolbe T, Breitbach M, Addicks K, et al. Interestingly, multimerization of syndecan-4 is prevented by phosphorylation of its cytoplasmic tail by PKC-[delta] in response to FGF2 signaling ( ). Correlations of reduced HS levels in the GBM, increased heparanase expression and proteinuria were also made in patients with various kidney diseases such as diabetic nephropathy, further suggesting a putative barrier function for GBM HS ( ). A disintegrin and metalloproteinase 17 (ADAM17) mediates inflammation-induced shedding of syndecan-1 and -4 by lung epithelial cells Qu X, Carbe C, Tao C, Powers A, Lawrence R van Kuppevelt TH, Cardoso WV, Grobe K, Esko JD, Zhang X 2011.
