Heparan sulfate 6-O-sulfotransferase 3 (HS6ST3) is a member of the heparan sulfate sulfotransferase family, which plays a critical role in modifying heparan sulfate (HS) proteoglycans. HS chains are linear polysaccharides attached to core proteins, functioning as key regulators of cell signaling, extracellular matrix interactions, and molecular recognition. HS6ST3 specifically catalyzes the transfer of sulfate groups to the 6-O position of glucosamine residues within HS, influencing the structural diversity and functional specificity of these glycans. This enzymatic modification is essential for mediating ligand-receptor interactions, including growth factors (e.g., FGFs, VEGF) and morphogens, thereby regulating developmental processes, cell proliferation, and tissue homeostasis.
The HS6ST3 gene is located on human chromosome 13q31.3 and is expressed in various tissues, with notable activity in the brain, pancreas, and reproductive organs. Its recombinant protein form is engineered for in vitro studies to investigate HS sulfation patterns, enzymatic mechanisms, and roles in disease contexts. Dysregulation of HS6ST3 has been linked to pathological conditions such as cancer, metabolic disorders, and neurological abnormalities. For instance, altered HS6ST3 expression may affect tumor angiogenesis or insulin signaling pathways, making it a potential therapeutic target.
Recombinant HS6ST3 is typically produced using mammalian or insect cell systems to ensure proper post-translational modifications. It serves as a tool for biochemical assays, structural studies, and drug discovery aimed at modulating HS-dependent pathways. Research on HS6ST3 also contributes to understanding developmental defects and designing glycan-based therapeutics targeting HS-protein interactions.
