== Function ==
 +
[https://www.uniprot.org/uniprot/LAMA2_MOUSE LAMA2_MOUSE] 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 ==
 +
The laminins are large heterotrimeric glycoproteins with fundamental roles in basement membrane architecture and function. The C-terminus of the laminin alpha chain contains a tandem of five laminin G-like (LG) domains. We report the 2.0 A crystal structure of the laminin alpha2 LG4-LG5 domain pair, which harbours binding sites for heparin and the cell surface receptor alpha-dystroglycan, and is 41% identical to the laminin alpha1 E3 fragment. LG4 and LG5 are arranged in a V-shaped fashion related by a 110 degrees rotation about an axis passing near the domain termini. An extended N-terminal segment is disulfide bonded to LG5 and stabilizes the domain pair. Two calcium ions, one each in LG4 and LG5, are located 65 A apart at the tips of the domains opposite the polypeptide termini. An extensive basic surface region between the calcium sites is proposed to bind alpha-dystroglycan and heparin. The LG4-LG5 structure was used to construct a model of the laminin LG1-LG5 tandem and interpret missense mutations underlying protein S deficiency.
