Specific sites or molecular structures on or in cells with which fibronectins react or to which they bind. Studies have shown that these receptors function in certain types of adhesive contact as well as playing a major role in matrix assembly. These are the traditional fibronectin receptors, also called VLA-5 receptors or alpha 5 beta 1 integrins. There are also other integrins that bind fibronectin, including alpha v beta 1.
