FunctionCell surface proteoglycan that may bear heparan sulfate (By similarity). May have a role in the organization of cell shape by affecting the actin cytoskeleton, possibly by transferring signals from the cell surface in a sugar-dependent mechanism.
Tissue specificityExpressed in the nervous system, the adrenal gland, and the spleen.
Sequence similaritiesBelongs to the syndecan proteoglycan family.
Post-translational modificationsO-glycosylated within the Thr/Ser-rich region which could interact with lectin domains on other molecules.
