  ABSTRACT  
 
Basement membranes are fundamental to tissue organization and physiology in all metazoans. The interaction between laminin and nidogen is crucial to the assembly of basement membranes. The structure of the interacting domains reveals a six-bladed Tyr-Trp-Thr-Asp (YWTD) beta-propeller domain in nidogen bound to laminin epidermal-growth-factor-like (LE) modules III3-5 in laminin (LE3-5). Laminin LE module 4 binds to an amphitheatre-shaped surface on the pseudo-6-fold axis of the beta-propeller, and LE module 3 binds over its rim. A Phe residue that shutters the water-filled central aperture of the beta-propeller, the rigidity of the amphitheatre, and high shape complementarity enable the construction of an evolutionarily conserved binding surface for LE4 of unprecedentedly high affinity for its small size. Hypermorphic mutations in the Wnt co-receptor LRP5 (refs 6-9) suggest that a similar YWTD beta-propeller interface is used to bind ligands that function in developmental pathways. A related interface, but shifted off-centre from the pseudo-6-fold axis and lacking the shutter over the central aperture, is used in the low-density lipoprotein receptor for an intramolecular interaction that is regulated by pH in receptor recycling.

Figure 2: The nidogen beta--propeller complex with laminin modules LE3 -5 and comparison with the LDLR beta--propeller. a, Ribbon diagram of the complex. -strands are numbered on one -propeller -sheet. The two disulphide connections are black. b, Superposition of LE modules 3 (cyan), 4 (magenta), and 5 (grey). Disulphide connections are thin bonds in the same colour; Asp 800, Asn 802 and Val 804 side chains of LE4 are shown in a and b. c, Superposition of nidogen and LDLR23 -propellers showing -sheets 1 and 5. The C trace backbones, side chains and water molecules in the central channel are shown in gold (nidogen) and green (LDLR). Side chains in the hydrophobic shutter in nidogen and equivalent residues in LDLR are shown. The four water molecules present in LDLR and absent in nidogen are marked with arrows. Dashed lines in a and c represent the pseudo-6-fold axis. 		Figure 4.
Figure 4: The nidogen -laminin interaction and comparison with the interaction in the LDLR. a, Stereo view of the nidogen interaction with LE4 and the adjacent portion of LE3. LE3 and LE4 are as in Fig. 2a. Portions of the nidogen backbone as C -trace and side chains forming the amphitheatre are shown in gold. Green dashed lines represent hydrogen bonds. b, C trace representation of the nidogen -laminin and intrinsic LDLR interactions. The propeller axes are vertical in the page. For clarity, the views are towards -propeller blade 1 in nidogen and blade 6 in LDLR. c, GRASP surfaces. Atoms within 4 Å of an interaction partner are shown in magenta (LE4 and LA4) and cyan (LE3 and LA5). The -propeller domains are viewed down their 6-fold axes. In the open book representation, the interacting LE3 -4 or LA4 -5 module pairs are rotated through 180° in the horizontal plane of the page. -propeller blades are numbered.

The most recent references are shown first. Citation data come partly from CiteXplore and partly from an automated harvesting procedure. Note that this is likely to be only a partial list as not all journals are covered by either method. However, we are continually building up the citation data so more and more references will be included with time. Where a reference describes a PDB structure, the PDB code is shown on the right.
