Regulation of Notch signaling by Drosophila heparan sulfate 3-O sulfotransferase
Heparan sulfate (HS) regulates the activity of various ligands and is involved in molecular recognition events on the cell surface and in the extracellular matrix. Specific binding of HS to different ligand proteins depends on the sulfation pattern of HS. For example, the interaction between antithrombin and a particular 3-O sulfated HS motif is thought to modulate blood coagulation. However, a...
متن کاملOverexpression of heparan sulfate 6-O-sulfotransferase-2 in colorectal cancer
The heparan sulfate sulfotransferase gene family catalyzes the transfer of sulfate groups to heparan sulfate and regulates various growth factor-receptor signaling pathways. However, the involvement of this gene family in cancer biology has not been elucidated. It was demonstrated that the heparan sulfate D-glucosaminyl 6-O-sulfotransferase-2 (HS6ST2) gene is overexpressed in colorectal cancer ...
متن کاملHeparan sulfate 6-o-sulfotransferase is essential for muscle development in zebrafish.
Heparan sulfate proteoglycans function in development and disease. They consist of a core protein with attached heparan sulfate chains that are altered by a series of carbohydrate-modifying enzymes and sulfotransferases. Here, we report on the identification and characterization of a gene encoding zebrafish heparan sulfate 6-O-sulfotransferase (hs6st) that shows high homology to other heparan s...
متن کاملUndersulfated heparan sulfate in a Chinese hamster ovary cell mutant defective in heparan sulfate N-sulfotransferase.
Heparan sulfate N-sulfotransferase catalyzes the transfer of sulfate groups from adenosine 3'-phosphate, 5'-phosphosulfate to the free amino groups of glucosamine residues in heparan sulfate. We have identified a Chinese hamster ovary cell mutant, designated pgsE-606, which is 3-5-fold defective in N-sulfotransferase activity. The residual enzyme activity is indistinguishable from the wild-type...
متن کاملStem domains of heparan sulfate 6-O-sulfotransferase are required for Golgi localization, oligomer formation and enzyme activity.
Heparan sulfate O-sulfotransferases catalyze the O-sulfation of the glucosamine and uronic acid residues of heparan sulfate, thereby determining the binding sites for ligands necessary for important biological functions such as the formation of morphogen gradients and growth factor signaling. Here we investigated the localization of the three heparan sulfate 6-O-sulfotransferase (HS6ST) isoform...
