CAS 125720-21-0: fibronectin adhesion-promoting peptide

Heparin-binding peptide aids adhesion, part of fibronectin's carboxy-terminal domain.

Fibronectin Adhesion-Promoting Peptide trifluoroacetate salt H-Trp-Gln-Pro-Pro-Arg-Ala-Arg-Ile-OH trifluoroacetate salt (FAP) is a synthetic peptide that promotes fibronectin adhesion. It binds to the amino acid sequence in the C terminal end of fibronectin, which is known to be responsible for binding to actin filaments and growth factors. FAP has been shown to promote wound healing by stimulating the proliferation of corneal epithelial cells in vitro. The mechanism of action of FAP may be due to its ability to bind to chloride ions, which are involved in the regulation of cell proliferation and migration.

The octapeptide Peptide V, WQPPRARI, constitutes one of the heparin-binding amino acid sequences found in the carboxy-terminal heparin-binding domain of fibronectin. The ovalbumin-coupled peptide is able to support cell attachment, and both the ovalbumin-coupled and the free peptides are potent inducers of focal adhesion formation.

Fibronectin Adhesion-Promoting Peptide is a polyclonal antibody that recognizes fibronectin, a glycoprotein found in the extracellular matrix. Fibronectin promotes cell adhesion and proliferation by binding to collagen. This antibody can be used to detect fibronectin in tissues from patients with cancer. It may also be used as a tool for identifying cancer cells that have metastasized to other sites in the body.
