Fibronectin Adhesion-promoting Peptide acetate (Heparin Binding Peptide acetate) is one of the heparin-binding amino acid sequences found in the carboxy-terminal heparin-binding domain of fibronectin.

GRGDS and Fibronectin Adhesion-promoting Peptide (Heparin Binding Peptide: WQPPRARI) micropatterns increase the endothelialisation of prosthetic materials in vitro. Fibronectin Adhesion-promoting Peptide also enhances haptotactic cell migration. The anti-apoptotic effects of fibronectin require the presence of the WQPPRARI sequence, which may be due to synergistic survival signals mediated by this sequence and by the RGD motif[1]. RDGS and Fibronectin Adhesion-promoting Peptide promote cell adhesion through different activation pathways that induce different forms of adhesion which can be highlighted through the analysis of focal and fibrillar contacts[2].
