The RGD containing site of the mouse laminin A chain is active for cell attachment, spreading, migration and neurite outgrowth.

The laminin A chain has been sequenced by cDNA cloning and was found to contain an RGD sequence. Synthetic peptides containing the RGD sequence and flanking amino acids were active in mediating cell adhesion, spreading, migration, and neurite outgrowth. Furthermore, endothelial cell attachment to a laminin substrate was inhibited by an RGD-containing synthetic peptide.
