Several 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 کاملMorphometrical Study of Polysialylated Neural Cell Adhesion Molecule Positive Cells in Rat Pups Hippocampus Following Induction of Seizure during Pregnancy
Background:The polysialylated neural cell adhesion molecule (PSA-NCAM) is expressed in developing brain. Fetal brain damage is caused by different conditions such as seizure and hypoxia. The present study was designed to investigate the effect of maternal seizures on the number of PSA-NCAM positive cells in pup's hippocampus. Methods: Female Wistar rats were divided into four groups: (a) kindle...
متن کاملDifferent extracellular domains of the neural cell adhesion molecule (N- CAM) are involved in different functions
The neural cell adhesion molecule (N-CAM) engages in diverse functional roles in neural cell interactions. Its extracellular part consists of five Ig-like domains and two fibronectin type III homologous (type III) repeats. To investigate the functional properties of the different structural domains of the molecule in cell interactions and signal transduction to the cell interior, we have synthe...
متن کاملAssociation between the first two immunoglobulin-like domains of the neural cell adhesion molecule N-CAM.
The extracellular domain of N-CAM contains five immunoglobulin-like (Ig) and two fibronectin type III-like domains and facilitates cell-cell binding through multiple, weak interdomain interactions. NMR spectroscopy indicated that the two N-terminal Ig-like domains from chicken N-CAM (Ig I and Ig II) interact with millimolar affinity. Physico-chemical studies show that this interaction is signif...
متن کاملChanges in neural cell adhesion molecule (NCAM) structure during vertebrate neural development.
Changes in carbohydrate and polypeptide form of the neural cell adhesion molecule (NCAM) have been documented during the development of central nervous system tissue in both chicken and frog. The carbohydrate variations reflect a high and low content of polysialic acid, and for the two vertebrates examined the expression of these forms is similar. At very early stages of neural development NCAM...
