The cytoplasmic domain of the syndecan family of heparan sulfate proteoglycans is punctuated by the presence of four regularly spaced tyrosine residues. In this report, we explore the possibility of whether the four tyrosine residues in the cytoplasmic domain of N-syndecan (Syndecan 3) are potential substrates for phosphorylation by a tyrosine kinase. Bacterially expressed elk kinase was used to phosphorylate a series of bacterially expressed N-syndecan fusion proteins. Our results clearly demonstrate that the tyrosine residues in the cytoplasmic domain of N-syndecan can be phosphorylated by a tyrosine-specific kinase, and that all four tyrosine residues are capable of being phosphorylated.
