CC   -!- FUNCTION: Binding to cells via a high affinity receptor, laminin is
CC       thought to mediate the attachment, migration and organization of cells
CC       into tissues during embryonic development by interacting with other
CC       extracellular matrix components.
CC   -!- SUBUNIT: Laminin is a complex glycoprotein, consisting of three
CC       different polypeptide chains (alpha, beta, gamma), which are bound to
CC       each other by disulfide bonds into a cross-shaped molecule comprising
CC       one long and three short arms with globules at each end.
CC   -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular
CC       matrix, basement membrane. Note=Major component.
