FUNCTION: [Summary is not available for the mouse gene. This summary is for the human ortholog.] This gene encodes one of the vertebrate laminin alpha chains. Laminins, a family of extracellular matrix glycoproteins, are the major noncollagenous constituent of basement membranes. They have been implicated in a wide variety of biological processes including cell adhesion, differentiation, migration, signaling, neurite outgrowth and metastasis. Laminins are composed of 3 non identical chains: laminin alpha, beta and gamma (formerly A, B1, and B2, respectively) and they form a cruciform structure consisting of 3 short arms, each formed by a different chain, and a long arm composed of all 3 chains. Each laminin chain is a multidomain protein encoded by a distinct gene. The protein encoded by this gene is the alpha-5 subunit of of laminin-10 (laminin-511), laminin-11 (laminin-521) and laminin-15 (laminin-523). [provided by RefSeq, Jun 2013]
PHENOTYPE: Homozygotes for a targeted null mutation exhibit disrupted basal laminae leading to exencephaly, syndactyly, placentopathy, kidney defects, abnormal lobar septation with absence of a visceral pleural membrane, and lethality in late gestation. [provided by MGI curators]
