  • 功能：
    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.; Laminin-5 is thought to be involved in (1) cell adhesion via integrin alpha-3/beta-1 in focal adhesion and integrin alpha-6/beta-4 in hemidesmosomes, (2) signal transduction via tyrosine phosphorylation of pp125-FAK and p80, (3) differentiation of keratinocytes.

Seventeen percent of the patients were compound heterozygous or homozygous for mutations in the gene LAMA3, 59% carried mutations in both alleles of LAMB3, and 12% were homozygous for mutations in LAMC2.
