Heparan sulfate glucosamine 3-O-sulfotransferase 2 is an enzyme that in humans is encoded by the HS3ST2gene.[5][6]
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. This gene is expressed predominantly in brain and may play a role in the nervous system.[6]
Role in breast cancer
The HS3ST2 promoter is hypermethylated in breast cancer tissue compared to normal breast ducts, suggesting a potential involvement in the pathogenesis of the disease.[7] Functional analysis revealed that upregulation of HS3ST2 in human breast cancer cells resulted in altered invasiveness, which was due to changes in Mitogen-activated protein kinase signaling and matrix metalloproteinase expression.[8]
