Native fibronectin is composed of two subunits which are linked through two interchain disulfide bonds near the COOH-terminal of each subunit. The transglutaminase (factor XIIIa) crosslinking site is indicated by the arrow. Various macromolecular binding domains, including heparin (HEP), fibrin (FBN), and collagen are shown. The cell adhesion site (CELL) which possesses an RGDS sequence is depicted.
