Abstract
<p class="first" id="d9141445e49">The ability of fibronectin to bind cells can be
accounted for by the tetrapeptide
L-arginyl-glycyl-L-aspartyl-L-serine, a sequence which is part of the cell attachment
domain of fibronectin and present in at least five other proteins. This tetrapeptide
may constitute a cellular recognition determinant common to several proteins.
