Cell 4:783-792(1999). CC -!- FUNCTION: Binding to cells via a high affinity receptor, laminin CC is thought to mediate the attachment, migration and organization CC of cells into tissues during embryonic development by interacting CC with other extracellular matrix components. CC -!- SUBUNIT: Laminin is a complex glycoprotein, consisting of three CC different polypeptide chains (alpha, beta, gamma), which are bound CC to each other by disulfide bonds into a cross-shaped molecule CC comprising one long and three short arms with globules at each CC end. Alpha-2 is a subunit of laminin-2 (merosin) and laminin-4 (S- CC merosin). Interacts with FBLN1, FBLN2 and NID2. CC -!- SUBCELLULAR LOCATION: Secreted, extracellular space, extracellular CC matrix, basement membrane. Note=Major component. CC -!- DOMAIN: The alpha-helical domains I and II are thought to interact CC with other laminin chains to form a coiled coil structure. CC -!- DOMAIN: Domains VI, IV and G are globular. CC -!- DISEASE: Defects in Lama2 are a cause of murine muscular dystrophy CC (dy2J). CC -!- SIMILARITY: Contains 17 laminin EGF-like domains. CC -!- SIMILARITY: Contains 5 laminin G-like domains. CC -!- SIMILARITY: Contains 2 laminin IV type A domains. CC -!- SIMILARITY: Contains 1 laminin N-terminal domain.
