A typical proteoglycan is made of a core protein with covalently attached glycosaminoglycan (GAG) chains. Proteoglycans are a complex group of heavily glycosylated proteins that play a number of important structural and signaling roles 1. This demonstrates the existence of core protein-determined HS sulfation patterns that regulate specific biological activities.

The increased Sdc2 HS chains 6-O sulfation is driven by a specific N-terminal domain sequence the insertion of this sequence in Sdc4 N-terminal domain increases 6-O sulfation of its HS chains and promotes Sdc2-VEGFA 165-VEGFR2 complex formation. These differences are due to a significantly higher 6-O sulfation level in Sdc2 versus Sdc4 heparan sulfate (HS) chains, leading to an increase in VEGFA 165 binding sites and formation of a ternary Sdc2-VEGFA 165-VEGFR2 complex which enhances VEGFR2 activation.

No such abnormalities are observed in mice with deletion of the closely related Syndecan-4 (Sdc4) gene. Here we report that mice with global and inducible endothelial-specific deletion of Sdc2 display marked angiogenic and arteriogenic defects and impaired VEGFA 165 signaling. The proteoglycan Syndecan-2 (Sdc2) has been implicated in regulation of cytoskeleton organization, integrin signaling and developmental angiogenesis in zebrafish.
