Physical and functional association between TNIIIA2-stimulated integrin α5β1 and PDGF receptor (PDGF-R). Peptide TNIIIA2 induces integrin α5β1 activation through a lateral association with syndecan-4, facilitating the formation of a molecular complex that includes activated integrin α5β1, syndecan-4, and activated PDGF-R in cholesterol- and caveolin-enriched membrane microdomains, which results in an enhanced activation of PDGF-R and leads to the hyperstimulation of cell proliferation.
