– RGD peptide (GRGDNP) TFA functions as an inhibitor of integrin-ligand interactions, competitively blocking α5β1’s interaction with the extracellular matrix (ECM). It induces apoptosis by triggering conformational changes that facilitate pro-caspase-3 activation and autoprocessing. Furthermore, RGD peptide (GRGDNP) TFA is critical in regulating cell adhesion, migration, growth, and differentiation [1] [2] [3].
