Laminin β2 (Engelbreth-Holm-Swarm murine sarcoma basement membrane) is a crucial structural component in animal tissues, forming part of the framework that supports tissue architecture. It interacts with type IV collagen through entactin and basement membrane proteoglycans and associates with cell membranes via integrin receptors, dystroglycan complexes, and Lutheran blood group glycoproteins. Additionally, it contains functional domains that facilitate collagen binding, cell adhesion, heparin interactions, and promote neurite outgrowth.
