General annotation (Comments)
| Function | 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. Ladsin exerts cell-scattering activity toward a wide variety of cells, including epithelial, endothelial, and fibroblastic cells. Ref.7 |
| Subunit structure | 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. Gamma-2 is a subunit of laminin-5 (laminin-332 or epiligrin/kalinin/nicein). |
| Subcellular location | Secreted › extracellular space › extracellular matrix › basement membrane. Note: Major component. |
| Tissue specificity | The large variant is expressed only in specific epithelial cells of embryonic and neonatal tissues. In 17-week old embryo the small variant is found in cerebral cortex, lung, and distal tubes of kidney, but not in epithelia except for distal tubuli. |
| Domain | The alpha-helical domains I and II are thought to interact with other laminin chains to form a coiled coil structure. Domain IV is globular. |
| Involvement in disease | Defects in LAMC2 are a cause of epidermolysis bullosa junctional Herlitz type (H-JEB) [MIM:226700]; also known as junctional epidermolysis bullosa Herlitz-Pearson type. JEB defines a group of blistering skin diseases characterized by tissue separation which occurs within the dermo-epidermal basement membrane. H-JEB is a severe, infantile and lethal form. Death occurs usually within the first six months of life. Occasionally, children survive to teens. H-JEB is marked by bullous lesions at birth and extensive denudation of skin and mucous membranes that may be hemorrhagic. |
| Miscellaneous | Binds heparin By similarity. |
| Sequence similarities | Contains 8 laminin EGF-like domains. Contains 1 laminin IV type A domain. |
