Characterization of regions of fibronectin besides the arginine-glycine-aspartic acid sequence required for adhesive function of the cell-binding domain using site-directed mutagenesis.

Abstract excerpt

Previous studies of adhesion mediated by the central cell-binding domain of fibronectin suggest that additional polypeptide information besides the Arg-Gly-Asp sequence is required for full activity. We analyzed this putative second, synergistic region of fibronectin more extensively by deletion analysis and oligonucleotide-based site-directed mutagenesis. Resulting mutated fusion proteins expressed using lambda...
