    The polymerization of laminin into a cell-associated network--a key step in basement membrane assembly--is mediated by the laminin amino-terminal (LN) domains at the tips of the three short arms of the laminin αβγ-heterotrimer. The crystal structure of a laminin α5LN-LE1-2 fragment shows that the LN domain is a β-jelly roll with several elaborate insertions that is attached like a flower head to the stalk-like laminin-type epidermal growth factor-like tandem. A surface loop that is strictly conserved in the LN domains of all α-short arms is required for stable ternary association with the β- and γ-short arms in the laminin network.
