1.MECHANISM OF ACTION

Fibronectin Type III Connecting Segment (1-25) functions by binding specifically to integrin receptors, particularly α4β1 (VLA-4) and α5β1, on cell surfaces. This interaction triggers intracellular signaling cascades involving focal adhesion kinase (FAK) and mitogen-activated protein kinases (MAPKs), promoting cell adhesion, spreading, and migration. The peptide competitively inhibits native fibronectin binding, enabling precise modulation of cell-matrix interactions in experimental models. Its conserved sequence within the CS-1 region of fibronectin ensures high-affinity receptor engagement and reproducible biological effects.
