  • 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.
  • Tissue specificity

    Found in the basement membranes (major component).
  • Involvement in disease

    Defects in LAMB3 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.
    Defects in LAMB3 are a cause of generalized atrophic benign epidermolysis bullosa (GABEB) [MIM:226650]. GABEB is a non-lethal, adult form of junctional epidermolysis bullosa characterized by life-long blistering of the skin, associated with hair and tooth abnormalities.
  • Sequence similarities

    Contains 6 laminin EGF-like domains.
    Contains 1 laminin N-terminal domain.
  • Domain

    The alpha-helical domains I and II are thought to interact with other laminin chains to form a coiled coil structure.
    Domain VI is globular.
  • Cellular localization

    Secreted > extracellular space > extracellular matrix > basement membrane.
