Abstract
Syndecans are cell surface proteoglycans involved in cell adhesion and motility. Syndecan-4 is an important component of focal adhesions and is involved in cytoskeletal reorganisation. Previous work has shown that the syndecan-4 ectodomain can support cell attachment. Here, three vertebrate syndecan-4 ectodomains are compared including that of the zebrafish and we demonstrate that the cell binding activity of the syndecan-4 ectodomain is conserved. Cell adhesion to the syndecan-4 ectodomain appears to be a characteristic of mesenchymal cells. Comparison of syndecan-4 ectodomain sequences lead to the identification of three conserved regions of sequence of which one, an NXIP motif, is important for cell binding activity. We show that cell adhesion to the syndecan-4 ectodomain involves ss1 integrins in several cell types.
