Laminins are basement membrane, extracellular matrix glycoproteins that are composed of alpha, beta and gamma heterotrimeric chains. Different combinations of five alpha chains, three beta chains, and two gamma chains form at least 12 laminin isoforms. Laminin subunit alpha-4 contains the C-terminal G domain, and although implicated in developmental regulation due to expression profiles, the biological function of laminin subunit alpha-4 is yet to be fully understood. Laminis as a whole play an important role in cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. High expression has been observed in adult heart, lung, ovary, small and large intestines, placenta, and liver, with lower levels observed in skeletal muscle, kidney, pancreas, testis, prostate, and rain.
