'''NMR STUDY OF A PAIR OF FIBRILLIN CA2+ BINDING EPIDERMAL GROWTH FACTOR-LIKE DOMAINS, 22 STRUCTURES'''<br />

==Overview==
The nuclear magnetic resonance structure of a covalently linked pair of, calcium-binding (cb) epidermal growth factor-like (EGF) domains from human, fibrillin-1, the protein defective in the Marfan syndrome, is described., The two domains are in a rigid, rod-like arrangement, stabilized by, interdomain calcium binding and hydrophobic interactions. We propose a, model for the arrangement of fibrillin monomers in microfibrils that, reconciles structural and antibody binding data, and we describe a set of, disease-causing mutations that provide the first clues to the specificity, of cbEFG interactions. The residues involved in stabilizing the domain, linkage are highly conserved in fibrillin, fibulin, thrombomodulin, and, the low density lipoprotein receptor. We propose that the relative, orientation of tandem cbEGF domains in these proteins is similar, but that, in others, including Notch, pairs adopt a completely different, conformation.
