Nidogen,for example, cross-links two central components of thebasal lamina by binding to the laminin γ-1 chain and totype IV collagen. Given such a key role, it was surprisingthat mice with a homozygous knockout of the gene fornidogen-1 were entirely healthy, with no abnormal phe-notype. Similarly, mice homozygous for a knockout of thegene for nidogen-2 also appeared completely normal. Bycontrast, mice that were homozygous for a defined muta-tion in the gene for laminin γ-1, which eliminated just thebinding site for nidogen, died at birth with severe defectsin lung and kidney formation. The mutant portion of thelaminin γ-1 chain is thought to have no other functionthan to bind nidogen, and does not affect laminin struc-ture or its ability to assemble into the basal lamina.…
