SOLUTION STRUCTURE OF 6F11F22F2, A COMPACT THREE-MODULE FRAGMENT OF THE GELATIN-BINDING DOMAIN OF HUMAN FIBRONECTIN

Overview

The solution structure of the (6)F1(1)F2(2)F2 fragment from the, gelatin-binding region of fibronectin has been determined (Protein Data, Bank entry codes 1e88 and 1e8b). The structure reveals an extensive, hydrophobic interface between the non-contiguous (6)F1 and (2)F2 modules., The buried surface area between (6)F1 and (2)F2 ( approximately 870 A(2)), is the largest intermodule interface seen in fibronectin to date. The, dissection of (6)F1(1)F2(2)F2 into the (6)F1(1)F2 pair and (2)F2 results, in near-complete loss of gelatin-binding activity. The hairpin topology of, (6)F1(1)F2(2)F2 may facilitate intramolecular contact between the matrix, assembly regions flanking the gelatin-binding domain. This is the first, high-resolution study to reveal a compact, globular arrangement of modules, in fibronectin. This arrangement is not consistent with the view that, fibronectin is simply a linear 'string of beads'.

Disease

Known diseases associated with this structure: Ehlers-Danlos syndrome, type X, 225310 (1) OMIM:[135600]
