Syndecan-4 ELISA

The syndecan family contains four members (syndecan-1/syndecan, syndecan-2/fibroglycan, syndecan-3/N-syndecan, syndecan-4/ryudocan (amphyglycan)), which are transmembrane heparan sulfate proteoglycans (HSPGs). These HSPGs exhibit cell type-specific distribution with vascular endothelial cells expressing syndecan-1, -2, and -4, and predominant targeting to basolateral surfaces. The syndecan family members are type I integral membrane proteins with homologous transmembrane and cytoplasmic domains. The combined transmembrane/cytoplasmic domains contain four well-conserved tyrosine residues, which might serve important roles for biological function. The cytoplasmic tail of syndecan-4 interacts with focal adhesion molecules. Thus, syndecan-4 is known to have various biological functions such as anticoagulation, cell adhesion and cell multiplication. Separate control set available on request
