MGI Phenotype Strain: 3624772; 1934917
Lethality: E1-E17
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]

Protein Function and Prediction

Lama5 encodes LAMA5, a member of the alpha subfamily of vertebrate laminin chains (1). The laminins are localized to basement membranes and are required to maintain tissue homeostasis (2). Studies have shown that LAMA5 can regulate Wnt and P13K signaling in a cell-type specific manner (2).

Expression/Localization

LAMA5 RNA is ubiquitously expressed in human tissues, with highest levels in the lung, heart, and kidney (1). Another study determined by Northern blot analysis that LAMA5 is expressed in human placenta, heart, lung, skeletal muscle, kidney, and pancreas (3). Nagase et al. determined by RT-PCR that the highest LAMA5 expression was in the kidney, placenta, and lung; lower expression was observe in all other tissues except spleen, which did not show expression (4). Another study by Nagase et al. found that LAMA5 expression was ubiquitous with highest expression in the kidney and cerebellum (5).

Background

Lama5Gt1Jhm/Gt1Jhm; MGI:3624772

Not specified

Homozygotes in this genetic background exhibit complete lethality throughout fetal development along with abnormal embryo size, extraembryonic tissue morphology, limb/digit morphology, head/brain morphology, and lung morphology (6).

involves: 129S1/Sv * 129X1/SvJ * C57BL/6J

Homozygotes for a targeted null mutation exhibit disrupted basal laminae leading to exencephaly (7), syndactyly (7), placentopathy (7), renal/urinary system defects (e.g., small or absent kidney, absent ureter, attenuated ureteric branching) (8;9), abnormal lobar septation with absence of a visceral pleural membrane (10), excessive folding of the intestinal loops (9),  delayed neural tube closure (7), and lethality in late gestation (by E17) (7).
