== Function == | |||
[https://www.uniprot.org/uniprot/LAMA5_HUMAN LAMA5_HUMAN] Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. | |||

== Publication Abstract from PubMed == | |||
Laminins regulate diverse cellular functions through interaction with integrins. Two regions of laminins-three laminin globular domains of the alpha chain (LG1-3) and the carboxyl-terminal tail of the gamma chain (gamma-tail)-are required for integrin binding, but it remains unclear how the gamma-tail contributes to the binding. We determined the crystal structure of the integrin binding fragment of laminin-511, showing that the gamma-tail extends to the bottom face of LG1-3. Electron microscopic imaging combined with biochemical analyses showed that integrin binds to the bottom face of LG1-3 with the gamma1-tail apposed to the metal ion-dependent adhesion site (MIDAS) of integrin beta1. These findings are consistent with a model in which the gamma-tail coordinates the metal ion in the MIDAS through its Glu residue. | |||
