FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] Laminin, an extracellular protein, is a major component of the basement membrane. It is thought to mediate the attachment, migration, and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. It is composed of three subunits, alpha, beta, and gamma, which are bound to each other by disulfide bonds into a cross-shaped molecule. This gene encodes the alpha 2 chain, which constitutes one of the subunits of laminin 2 (merosin) and laminin 4 (s-merosin). Mutations in this gene have been identified as the cause of congenital merosin-deficient muscular dystrophy. Two transcript variants encoding different proteins have been found for this gene.

PHENOTYPE: Homozygotes for targeted and spontaneous mutations exhibit progressive growth retardation, ataxia, muscle atrophy and degeneration, infertility, and premature lethality. Muscle fiber degeneration is evident as early as the first week of life. [provided by MGI curators]
