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. Involved in the organization of the
CC laminar architecture of cerebral cortex. It is probably required for
CC the integrity of the basement membrane/glia limitans that serves as an
CC anchor point for the endfeet of radial glial cells and as a physical
CC barrier to migrating neurons. Radial glial cells play a central role in
CC cerebral cortical development, where they act both as the proliferative
CC unit of the cerebral cortex and a scaffold for neurons migrating toward
CC the pial surface. {ECO:0000269|PubMed:23472759}.
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. Beta-1 is a
CC subunit of laminin-1 (laminin-111 or EHS laminin), laminin-2 (laminin-
CC 211 or merosin), laminin-6 (laminin-311 or K-laminin), laminin-8
CC (laminin-411), laminin-10 (laminin-511) and laminin-12 (laminin-213).
CC Interacts with ITGB1 (By similarity). {ECO:0000250|UniProtKB:Q01635}.
CC -!- INTERACTION:

CC P07942; C5MBE7: CTRG_03389; Xeno; NbExp=2; IntAct=EBI-949174, EBI-16225951;
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 with
CC other laminin chains to form a coiled coil structure.
CC -!- DOMAIN: Domains VI and IV are globular.
CC -!- DISEASE: Lissencephaly 5 (LIS5) [MIM:615191]: An autosomal recessive
CC brain malformation characterized by cobblestone changes in the cortex,
CC more severe in the posterior region, and subcortical band heterotopia.
CC Affected individuals have hydrocephalus, seizures, and severely delayed
CC psychomotor development. {ECO:0000269|PubMed:23472759}. Note=The
CC disease is caused by variants affecting the gene represented in this
CC entry.
