Heparan sulfate 2-O-sulfotransferase 1

Gene

hs2st1

Organism
Xenopus laevis (African clawed frog)
Status
Reviewed-Annotation score: -Experimental evidence at transcript leveli

Functioni

Catalyzes the transfer of sulfate to the C2-position of selected hexuronic acid residues within the maturing heparan sulfate (HS). 2-O-sulfation within HS, particularly of iduronate residues, is essential for HS to participate in a variety of high-affinity ligand-binding interactions and signaling processes (By similarity).By similarity
