Previous GeneCards Identifiers for HS3ST3A1 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 is a type II integral membrane protein and possesses heparan sulfate glucosaminyl 3-O-sulfotransferase activity. The sulfotransferase domain of this enzyme is highly similar to the same domain of heparan sulfate D-glucosaminyl 3-O-sulfotransferase 3B1, and these two enzymes sulfate an identical disaccharide. This gene is widely expressed, with the most abundant expression in liver and placenta. [provided by RefSeq, Dec 2014]
GeneCards Summary for HS3ST3A1 Gene
HS3ST3A1 (Heparan Sulfate-Glucosamine 3-Sulfotransferase 3A1) 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 3 activity. An important paralog of this gene is HS3ST3B1.
UniProtKB/Swiss-Prot for HS3ST3A1 Gene
Sulfotransferase that utilizes 3-phospho-5-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to an N-unsubstituted glucosamine linked to a 2-O-sulfo iduronic acid unit on heparan sulfate. Catalyzes the O-sulfation of glucosamine in IdoUA2S-GlcNS and also in IdoUA2S-GlcNH2. The substrate-specific O-sulfation generates an enzyme-modified heparan sulfate which acts as a binding receptor to Herpes simplex virus-1 (HSV-1) and permits its entry. Unlike 3-OST-1, does not convert non-anticoagulant heparan sulfate to anticoagulant heparan sulfate.
