Fibronectin Analog CAS NO.125455-58-5

<p>Fibronectin Analog (CAS: 125455-58-5), also known as Fibronectin Fragment III1-C or FN III1-C, is a recombinant or synthetic peptide fragment derived from the first type III domain of fibronectin. This 30-40 amino acid sequence contains the RGD (Arg-Gly-Asp) motif and adjacent synergy sites that mimic the cell-binding domain of native fibronectin. It exhibits high affinity for integrin receptors (particularly α5β…

1.MECHANISM OF ACTION

The Fibronectin Analog functions primarily through integrin receptor binding via its RGD motif. The RGD sequence (Arg-Gly-Asp) directly interacts with the ligand-binding pocket of integrins α5β1 and αvβ3, triggering intracellular signaling cascades. This engagement leads to focal adhesion complex formation, activation of focal adhesion kinase (FAK), and recruitment of talin and vinculin to adhesion sites. Additionally, the synergy region adjacent to RGD enhances binding affinity and specificity for α5β1 integrin through conformational changes.

2.PRODUCT INDICATIONS
