    HS3ST3A1 Antibody (D-7) is a mouse monoclonal IgM antibody that detects HS3ST3A1 protein of mouse, rat, and human origin by western blotting (WB), immunoprecipitation (IP), immunofluorescence (IF), immunohistochemistry, and enzyme-linked immunosorbent assay (ELISA). Anti-HS3ST3A1 antibody (D-7) is available as a non-conjugated format. HS3ST3A1, also known as heparan sulfate (glucosamine) 3-O-sulfotransferase 3A1, plays a crucial role in heparan sulfate biosynthesis, a polysaccharide vital for various biological processes, including cell signaling, growth factor activity, and cell adhesion. HS3ST3A1 is a 406 amino acid single-pass type II membrane protein primarily localized in the Golgi apparatus, where HS3ST3A1 catalyzes sulfate group transfer to specific glucosamine residues on heparan sulfate chains. Proper functioning of HS3ST3A1 is essential for generating heparan sulfate structures that mediate interactions between cells and their environment, influencing processes such as tissue development and repair. HS3ST3A1 is expressed ubiquitously, with particularly high levels found in the placenta, heart, kidney, and liver, highlighting HS3ST3A1′s importance in various physiological contexts. The gene encoding HS3ST3A1 is located on human chromosome 17, a significant region encoding over 1,200 genes, underscoring the complexity and interconnectivity of biological systems.
