The neural cell adhesion molecule L1 potentiates integrin-dependent cell migration to extracellular matrix proteins.
The L1 adhesion molecule regulates axon growth and is mutated in the X-linked mental retardation syndrome CRASH (acronym for corpus callosum agenesis, retardation, aphasia, spastic paraplegia, hydrocephalus). A novel role for L1 as a potentiator of neuronal cell migration to extracellular matrix proteins through beta1 integrins and intracellular signaling to mitogen-activated protein (MAP) kina...
متن کاملThe neural cell adhesion molecule N-CAM enhances L1-dependent cell-cell interactions
On neural cells, the cell adhesion molecule L1 is generally found coexpressed with N-CAM. The two molecules have been suggested, but not directly shown, to affect each other's function. To investigate the possible functional relationship between the two molecules, we have characterized the adhesive interactions between the purified molecules and between cultured cells expressing them. Latex bea...
متن کاملClara cell adhesion and migration to extracellular matrix
BACKGROUND Clara cells are the epithelial progenitor cell of the small airways, a location known to be important in many lung disorders. Although migration of alveolar type II and bronchiolar ciliated epithelial cells has been examined, the migratory response of Clara cells has received little attention. METHODS Using a modification of existing procedures for Clara cell isolation, we examined...
متن کاملSeveral extracellular domains of the neural cell adhesion molecule L1 are involved in neurite outgrowth and cell body adhesion.
The neural cell adhesion molecule L1 is a multidomain protein that plays important roles in cell adhesion, migration, and neurite outgrowth. To analyze structure-function relationships of L1 in neurite outgrowth and cell body adhesion, we have expressed and purified a set of different fragments of the extracellular part of this glycoprotein in CHO cells and in Escherichia coli. When neurite out...
متن کاملHuman Neural Cell Adhesion Molecule L1 and Rat Homologue NILE are Ligands for Integrin
Integrin Otv~3 is distinct in its capacity to recognize the sequence Arg-Gly-Asp (RGD) in many extra-cellular matrix (ECM) components. Here, we demonstrate that in addition to the recognition of ECM components, ave3 can interact with the neural cell adhesion molecule L1-CAM; a member of the immunoglobulin superfamily (IgSF). M21 melanoma cells displayed significant Ca++-dependent adhesion and s...
