Binding properties of a cell adhesion molecule from neural tissue.

We have previously identified and purified a cell surface glycoprotein from retina and brain, called neural cell adhesion molecule or N-CAM, that appears to be involved in neural cell--cell adhesion, the fasciculation of neurites, and the formation of normal tissue patterns in the retina. The present studies reveal that artificial vesicles containing lipid and purified N-CAM bind to different c...

Regulation of cell adhesion by polysialic acid. Effects on cadherin, immunoglobulin cell adhesion molecule, and integrin function and independence from neural cell adhesion molecule binding or signaling activity.

The polysialylation of neural cell adhesion molecule (NCAM) evolved in vertebrates to carry out biological functions related to changes in cell position and morphology. Many of these effects involve the attenuation of cell interactions that are not mediated through NCAM's own adhesion properties. A proposed mechanism for this global effect on cell interaction is the steric inhibition of membran...

Morphometrical 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...

Cell surface modulation of the neural cell adhesion molecule resulting from alternative mRNA splicing in a tissue-specific developmental sequence

The neural cell adhesion molecule N-CAM is an intrinsic membrane glycoprotein that is expressed in the embryonic chicken nervous system as two different polypeptide chains encoded by alternatively spliced transcripts of a single gene. Because they differ by the presence or absence of approximately 250 amino acids in their cytoplasmic domains, these polypeptides are designated ld and sd, for lar...

Identification of a peptide sequence involved in homophilic binding in the neural cell adhesion molecule NCAM

The neural cell adhesion molecule NCAM is capable of mediating cell-cell adhesion via homophilic interactions. In this study, three strategies have been combined to identify regions of NCAM that participate directly in NCAM-NCAM binding: analysis of domain deletion mutations, mapping of epitopes of monoclonal antibodies, and use of synthetic peptides to inhibit NCAM activity. Studies on L cells...
