The Asp-Gly-Glu-Ala (DGEA) amino acid domain of type I collagen interacts with the α2β1 integrin receptor on the cell membrane and mediates extracellular signals into cells. It is a potential antagonist of collagen receptors.
α2β1 Integrin Ligand Peptide TFA interacts with integrin receptors on the cell membrane, mediating extracellular signaling and potentially acting as an antagonist of the collagen receptor.
