NIDOGEN-1 G2/PERLECAN IG3 COMPLEX
Overview
Nidogen and perlecan are large multifunctional basement membrane (BM), proteins conserved in all metazoa. Their high-affinity interaction, which, is likely to contribute to BM assembly and function, is mediated by the, central G2 domain in nidogen and the third immunoglobulin (IG)-like domain, in perlecan, IG3. We have solved the crystal structure at 2.0 A resolution, of the mouse nidogen-1 G2-perlecan IG3 complex. Perlecan IG3 belongs to, the I-set of the IG superfamily and binds to the wall of the nidogen-1 G2, beta-barrel using beta-strands C, D and F. Nidogen-1 residues, participating in the extensive interface are highly conserved, whereas the, corresponding binding site on perlecan is more variable. We hypothesize, that a second, as yet unidentified, activity of nidogen overlaps ... [(full description)]
