Structure and action of neural cell adhesion molecules in nervous system

Neural cell adhesion molecule(NCAM)is a kind of cell sur face glycoprotein that typically possesses immunoglobulin superfamily's characte r. NCAM mainly expresses in nervous system and mediates the interaction of cell- cell or cell-extracellular matrix initiated by their distinct isophil and hetero phile in Ig domains. It participates the development progress of nervous system and plays the important roles in it.
