I-DOMAIN FROM INTEGRIN CR3, MG2+ BOUND
Overview
We have determined the high resolution crystal structure of the A domain, from the alpha chain of integrin CR3. The domain adopts a classic, alpha/beta "Rossmann" fold and contains an unusual Mg2+ coordination site, at its surface. One of the coordinating ligands is the glutamate side, chain from another A domain molecule. We suggest that this site represents, a general metal ion-dependent adhesion site (MIDAS) for binding protein, ligands. We further propose that the beta subunits of integrins contain a, MIDAS motif within a modified A domain. Our crystal structure will allow, reliable models to be built for other members of the A domain superfamily, and should facilitate development of novel adhesion modulatory drugs.
