'''I DOMAIN FROM INTEGRIN ALPHA1-BETA1'''<br />


==Overview==
==I Domain from Integrin Alpha1-Beta1==
Most mammalian cells and some pathogenic bacteria are capable of adhering, to collagenous substrates in processes mediated by specific cell surface, adherence molecules. Crystal structures of collagen-binding regions of the, human integrin alpha(2)beta(1) and a Staphylococcus aureus adhesin reveal, a "trench" on the surface of both of these proteins. This trench can, accommodate a collagen triple-helical structure and presumably represents, the ligand-binding site (Emsley, J., King, S. L., Bergelson, J. M., and, Liddington, R. C. (1997) J. Biol.
