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.
Integrin modulator 1 is a potent and selective α4β1 integrin agonist, with an IC50 of 9.8 nM for RGD-binding α4β1. Integrin modulator 1 increases cell adhesion mediated by α4β1 integrin, with an EC50 of 12.9 nM[1]. Integrin modulator 1 (2-10 μg mL; 30 min) significantly increases Jurkat E6.1 cell adhesion[1].Integrin modulator 1 (1-100 nM; 1 h) strongly and significantly increases ERK1 2 phosphorylation in Jurkat E6.1 cells[1].Integrin modulator 1 (1 nM-10 μM; 30 min) significantly increases the binding of HUTS-21 antibody to Jurkat E6.1 cells in a concentration-dependent manner[1].
