Collagen Assembly at the Cell Surface: Dogmas Revisited

NettetThe main receptors with which collagen IV interacts are integrins and non-integrin receptors. On the other hand, peptides derived from collagen IV can disrupt the interaction with integrins, in particular with α5β1 integrin, and in parallel activate Ang2/Tie2 signa-ling pathway essential for maintaining vascular homeostasis . Nettet1 integrins in collagens have been localized to the triple helical areas of the molecules (8, 9). One peptide sequence derived from the collagen achain has been reported to block integrin-collagen interaction (10), but in many studies it has been ineffective and it probably does not represent the actual binding site in collagen (11–13).
