1 Introduction. Sialic acid  is the most abundant terminal monosaccharide on glycoconjugates of the eukaryotic cell surface. It is involved in a variety of cellular functions, such as cell–cell interaction, virus infection or the stability of glycoproteins .One prominent example of a highly sialylated glycoprotein is the neural cell adhesion molecule NCAM . Polysialylation is a rare posttranslational modification executed by the two enzymes ST8Sia II and ST8Sia IV ().These polysialyltransferases generate long α2,8-linked linear homopolymers of sialic acid, which are attached to N- and/or O-linked glycans ().Polysialylation is mainly known to control the developmental plasticity of the vertebrate nervous system by modulating cell-cell and cell.
Regulation. The fact that PSA can be rapidly expressed at the cell surface, 23, 27, 29 along with the demonstration of relatively fast changes in the morphology and contacts of cells expressing high amounts of PSA-NCAM, 34 raises the possibility that polysialylation may be involved in rapid modulation of cell surface interactions. Rapid conformational changes can affect neurons and glia.

The formation of appropriate neuronal circuits is an essential part of nervous system development and relies heavily on the outgrowth of axons and dendrites and their guidance to their respective targets. This process is governed by a large array of molecules, including glial cell line-derived neurotrophic factor (GDNF) and the neural cell adhesion molecule (NCAM), the interaction of which. of the Neural Cell Adhesion Molecule NCAM This book contains review articles that produce a snapshot of recent developments in the field of the neural cell adhesion molecule NCAM. The chapters are grouped into sections reflecting various aspects of NCAM structure and function. The themes cover the structural basis of cell adhe-.

The up- and downregulation of polysialic acid–neural cell adhesion molecule (PSA–NCAM) expression on motorneurons during development is associated respectively with target innervation and synaptogenesis, and is regulated at the level of PSA enzymatic biosynthesis involving specific polysialyltransferase by: T he polysialic acid component of neuronal cell adhesion molcule (NCAM) 1 serves as a temporally regulated modulator of a variety of cell interactions during development (for review see reference 38), with effects having been documented for the facilitation of guidance and targeting of axons (42, 43), migration of neuronal (15, 33), and glial precursors, and development of muscle myotubes ().Cited by: Neural cell adhesion molecule (NCAM) is a surface glycoprotein and is a member of the immunoglobulin superfamily of molecules.
There are three isoforms of NCAM, each of which is expressed differentially during development, undergoing posttranslational modification in phosphorylation and sulfation (Hoffman and Edelman, ). Neural cell adhesion molecule (NCAM, CD56) is a transmembrane glycoprotein modulating cell–cell and cell–matrix interactions.
An additional post-translational modification of NCAM is the α2,8. Regulation of Neural Cell Adhesion Molecule Polysialylation: Evidence for Nontranscriptional Control and Sensitivity to an Intracellular Pool of Calcium.

Among the large set of cell surface glycan structures, the carbohydrate polymer polysialic acid (polySia) plays an important role in vertebrate brain development and synaptic plasticity. The main carrier of polySia in the nervous system is the neural cell adhesion molecule NCAM.

Given that cell proliferation and migration from the niche is observed in liver regeneration, we hypothesized that the antagonistic functions of NCAM and polySia‐NCAM in the regulation of cell adhesion and cell migration (proven for the nervous tissue) may play a significant role during liver development and regeneration.
The gain of migratory properties reflects phenotypically in the expression of several epithelial and mesenchymal markers. 8, 9 Among them, the neural cell adhesion molecule (NCAM) is a surface glycoprotein that, in the nervous system, lung, and gut, regulates morphogenetic processes relative to cell migration and tissue differentiation and, in.

Journal of Neurochemis – In the hippocampus, morphological synaptic plasticity, supported by regulation of neural cell adhesion molecule (NCAM) polysialylation status, is crucial to information storage. The recent description of polysialylated neurons in the various fields of the medial PFC suggests these structures to possess a similar capacity for synaptic plasticity.Neural cell adhesion molecule (NCAM), also called CD56, is a homophilic binding glycoprotein expressed on the surface of neurons, glia and skeletal gh CD56 is often considered a marker of neural lineage commitment due to its discovery site, CD56 expression is also found in, among others, the hematopoietic system.
