NCIt definition : Neural cell adhesion molecule 1 (761 aa, 84 kDa) is encoded by the human NCAM1 gene.
This protein is involved in the mediation of neuron-neuron adhesion.;
NCIt note : Neural Cell Adhesion Molecule is a membrane-bound glycoprotein member of the Ig superfamily
that binds to a variety of other cell adhesion proteins involved in diverse contact-mediated
interactions. NCAM appears on early embryonic cells and is important in the formation
of cell collectives at sites of morphogenesis. Later it is found on differentiated
neurons, astrocytes, oligodendrocytes, and myotubes and mediates neuronal adhesion,
guidance, and differentiation. NCAM plays a role in cell-cell and cell-matrix adhesion
through homophilic and heterophilic binding. The invertebrate cell adhesion molecules
fasciclin II (grasshoppers and Drosophila) and apCAM (Aplysia) are related to NCAM
and can mediate homophilic cell aggregation. Four main isoforms exist, including CD56,
but many variants result from alternative splicing and post-translational modifications.;
