High affinity nidogen binding of laminin‐1 (chain composition α1β1γ1) has been previously mapped to a single EGF‐like motif γ1III4 of its γ1 chain. Two more isoforms, laminin‐5 (α3β3γ2) and laminin‐7 (α3β2γ1), show low and high binding activity, respectively, indicating that the γ2 chain is of low affinity. This was confirmed by recombinant production of the homologous EGF‐like motif γ2III4 of the γ2 chain, which has a 100,000‐fold lower binding activity than γ1III4. The crucial heptapeptide… Expand

Structural and Genetic Analysis of Laminin‐Nidogen Interaction
• Biology, Medicine
• Annals of the New York Academy of Sciences
• 1998
High‐affinity binding of nidogen to laminins involves a single binding site on the laminin γ1 chain and is thus a property shared by almost all laminationin isoforms, considered to be an essential step in the stabilization of basement membranes. Expand
Laminin γ3 Chain Binds to Nidogen and Is Located in Murine Basement Membranes*
• Biology, Medicine
• Journal of Biological Chemistry
• 2005
Two fragments of the novel laminin γ3 chain were expressed in mammalian cells recombinantly and suggested that laminins containing the γ2 chain may assemble networks independent of other laminationins. Expand
Characterization and Expression of the Laminin γ3 Chain: A Novel, Non-Basement Membrane–associated, Laminin Chain
The distribution of γ3-containing laminins on the apical surfaces of a variety of epithelial tissues is novel and suggests that they are not found within ultrastructurally defined basement membranes, which suggests that these apical lamination processes are important in the morphogenesis and structural stability of the ciliated processes of these cells.

Short arm region of laminin-5 gamma2 chain: structure, mechanism of processing and binding to heparin and proteins.
Immunological studies showed a similar partial processing in cell culture and tissues and the persistence of the released fragment in tissues indicated that both N-terminal regions of the gamma2 chain may have a function in vivo. Expand
Laminin 5 Binds the NC-1 Domain of Type VII Collagen
• Biology, Medicine
• The Journal of cell biology
• 1997
The results support a model predicting that monomeric laminin 5 constitutes the anchoring filaments and bridges integrin α6β4 with type VII collagen, and the laminationin 5–6/7 complexes are present within the interhemidesmosomal spaces bound at least by integrinα3β1 where they may mediate basement membrane assembly or stability, but contribute less significantly to epithelial friction resistance.

Crystal structure of three consecutive laminin-type epidermal growth factor-like (LE) modules of laminin gamma1 chain harboring the nidogen binding site.
• Chemistry, Medicine
• Journal of molecular biology
• 1996
The data demonstrate the unique nature of the LE modules and only a remote similarity to EGF and indicate that the crucial residues in the binding loops provide direct contacts with nidogen and explain the synergism between loops a and c which is essential for binding. Expand
Dimer model for the microfibrillar protein fibulin‐2 and identification of the connecting disulfide bridge
A dimer model is proposed indicating mainly a rod‐like shape of 80 nm length based on an anti‐parallel association of two subunits through their domains I, which implies alignment of domains II and N between different subunits. Expand
Bone Morphogenetic Protein 1 Is an Extracellular Processing Enzyme of the Laminin 5 γ2 Chain*
It is speculated that γ2 cleavage is required for formation of the laminin 5–6 complex and that this complex is directly involved in assembly of the interhemidesmosomal basement membrane, which suggests that BMP-1 activity facilitates basement membrane assembly, but not hemidesmosome assembly, in the laminationin 5-richdermal junction basement membrane in vivo.

A single EGF‐like motif of laminin is responsible for high affinity nidogen binding.
Smaller fragments were prepared by the same recombinant procedure and showed that combinations of EGF‐like repeats 3–4 and 4–5 and the single repeat 4 but not repeats 3 or 5 possess full nidogen‐binding activity, identifying repeat 4 as the only binding structure. Expand

The large pepsin fragments P1 and P1X, which comprise most of the rod-like domains III of the three short arms of laminin from the mouse Engelbreth-Holm-Swarm tumor, possess full binding activity for nidogen in radioligand assays, indicating that a major binding structure for ndogen is located within three or four cysteine-rich repeats occupying sequence positions 755 to about 920 in the B2 chain.

Two isoforms of laminin were extracted from human placenta by neutral buffer containing EDTA, copurified through several steps and finally separated by Mono Q anion exchange chromatography and showed a similar cross-shaped structure, indicating a crucial role for nidogen in mediating the integration of these laminationin isoforms into basement membranes.
