Previous GeneCards Identifiers for HS3ST1 Gene
Heparan sulfate biosynthetic enzymes are key components in generating a myriad of distinct heparan sulfate fine structures that carry out multiple biologic activities. The enzyme encoded by this gene is a member of the heparan sulfate biosynthetic enzyme family. It possesses both heparan sulfate glucosaminyl 3-O-sulfotransferase activity, anticoagulant heparan sulfate conversion activity, and is a rate limiting enzyme for synthesis of anticoagulant heparan. This enzyme is an intraluminal Golgi resident protein. [provided by RefSeq, Jul 2008]
GeneCards Summary for HS3ST1 Gene
HS3ST1 (Heparan Sulfate-Glucosamine 3-Sulfotransferase 1) is a Protein Coding gene. Among its related pathways are heparan sulfate biosynthesis and Glycosaminoglycan metabolism. GO annotations related to this gene include sulfotransferase activity and [heparan sulfate]-glucosamine 3-sulfotransferase 1 activity. An important paralog of this gene is HS3ST5.
UniProtKB/Swiss-Prot for HS3ST1 Gene
Sulfotransferase that utilizes 3-phospho-5-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to position 3 of glucosamine residues in heparan. Catalyzes the rate limiting step in the biosynthesis of heparan sulfate (HSact). This modification is a crucial step in the biosynthesis of anticoagulant heparan sulfate as it completes the structure of the antithrombin pentasaccharide binding site.
