Protein
Heparan sulfate 2-O-sulfotransferase hst-2
Organism
Caenorhabditis elegans
Function
Catalyzes the transfer of sulfate to the C2-position of selected hexuronic acid residues within the maturing heparan sulfate (HS). Involved in cell adhesion and guidance by specifically modifying proteoglycans in the extracellular matrix and on the cell surface that are essential for axon migrations.
Similarity
Belongs to the sulfotransferase 3 family.
