HS3ST4 (Heparan Sulfate-Glucosamine 3-Sulfotransferase 4): HS3ST4 is involved in the modification of heparan sulfate, a component of the extracellular matrix. This modification is crucial for various biological processes, including cell signaling and blood coagulation. Dysregulation of HS3ST4 may impact cellular interactions and has potential implications in cancer and vascular disorders....
