Background Information	Elements of the extracellular matrix such as laminins, a family of heterotrimeric extracellular glycoproteins, affect tissue development and integrity in organs including the kidney, lung, skin, and nervous system. Laminins function as heterotrimeric complexes of alpha, beta, and gamma chains, with each chain type representing a different subfamily of proteins. For example, the alpha subfamily of laminin chains is a major component of basement membranes. Two transcript variants encoding different isoforms have been found for this gene, but the full-length nature of one of them has not been determined. At least 15 distinct laminin trimers, containing various combinations of 5 alpha, 4 beta, and 3 gamma subunits have been found in mammals. Both laminin alpha 5 and alpha 1 are prevalent in kidney. Mice that are homozygous for a null mutation in the alpha 5 laminin gene are dead by embrionic day 14 - 19 with multiple developmental abnormalities. The kidney phenotypes include avascular glomeruli, impaired branching morphogenesis, and renal agenesis.

Entrez Gene Number	NM_000426.3
Entrez Gene Summary	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.
Gene Symbol	LAMA2 LAMM
Purification Method	Unpurified
UniProt Number	P24043
UniProt Summary	FUNCTION: SwissProt: P24043 # Binding to cells via a high affinity receptor, laminin is thought to mediate the attachment, migration and organization of cells into tissues during embryonic development by interacting with other extracellular matrix components. SIZE: 3110 amino acids; 342771 Da SUBUNIT: Laminin is a complex glycoprotein, consisting of three different polypeptide chains (alpha, beta, gamma), which are bound to each other by disulfide bonds into a cross-shaped molecule comprising one long and three short arms with globules at each end. Alpha-2 is a subunit of laminin-2 (merosin) and laminin-4 (S- merosin). SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular matrix, basement membrane. Note=Major component. TISSUE SPECIFICITY: Placenta, striated muscle, peripheral nerve, cardiac muscle, pancreas, lung, spleen, kidney, adrenal gland, skin, testis, meninges, choroid plexus, and some other regions of the brain; not in liver, thymus and bone. DOMAIN: SwissProt: P24043 The alpha-helical domains I and II are thought to interact with other laminin chains to form a coiled coil structure. & Domains VI, IV and G are globular. DISEASE: SwissProt: P24043 # Defects in LAMA2 are the cause of merosin-deficient congenital muscular dystrophy type 1A (MDC1A) [MIM:607855]. MDC1A is characterized by difficulty walking, hypotonia, proximal weakness, hyporeflexia, and white matter hypodensity on MRI. SIMILARITY: Contains 17 laminin EGF-like domains. & Contains 5 laminin G-like domains. & Contains 2 laminin IV type A domains. & Contains 1 laminin N-terminal domain.
Molecular Weight	80 kDa
