2-O-sulfotransferase regulates Wnt signaling, cell adhesion and cell cycle during zebrafish epiboly.

O-sulfotransferases modify heparan sulfate proteoglycans (HSPGs) by catalyzing the transfer of a sulfate to a specific position on heparan sulfate glycosaminoglycan (GAG) chains. Although the roles of specific HSPG modifications have been described in cell culture and invertebrates, little is known about their functions or abilities to modulate specific… CONTINUE READING
