Human Fibronectin III 1H,8-10 N-GST

This recombinant FN fragment corresponds to amino acids I597-T673 of type-III 1H joined to A1235-T1509 of type-III 8-10 by a GS linker. This fragment contains the N-terminal heprin binding domain region linked to the complete itegrin binding region of the peptide. The integrin region of the peptide is known to enhance cell attachment and adhesion.

Fibronectins (FN) are a family of high molecular weight, multidomain glycoproteins composed of two structurally similar subunits which are joined at the carboxyl terminus by disulfide bonds. The primary structure of FN is organized into three types of repeating homologous units, termed types I, II, and III. These modules in turn are organized into functional domains which have been shown to contain multiple binding sites, including those for sulfated glycosaminoglycans, gelatin, fibrin, and cell surface integrin receptors. Twelve type I modules are found grouped at the amino- and carboxyl-terminal regions, and two type II modules are located within the gelatin-binding region. Fifteen to seventeen type III modules are contained within the middle of the molecule and comprise 60% of fibronectin’s sequence.
