Polysialic acid

Index Polysialic acid

Polysialic acid is an unusual posttranslational modification that occurs on neural cell adhesion molecules (NCAM). [1]

5 relations: Ion, Neural cell adhesion molecule, Post-translational modification, Sialic acid, Synapse.

Ion

An ion is an atom or molecule that has a non-zero net electrical charge (its total number of electrons is not equal to its total number of protons).

Neural cell adhesion molecule

Neural cell adhesion molecule (NCAM), also called CD56, is a homophilic binding glycoprotein expressed on the surface of neurons, glia and skeletal muscle.

Synapse

In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target efferent cell.
