Neuronal cell adhesion molecule is a protein that in humans is encoded by the NRCAM gene.^[1]^[2]

Cell adhesion molecules (CAMs) are members of the immunoglobulin superfamily. This gene encodes a neuronal cell adhesion molecule with multiple immunoglobulin-like C2-type domains and fibronectin type-III domains. This ankyrin-binding protein is involved in neuron-neuron adhesion and promotes directional signaling during axonal cone growth. This gene is also expressed in non-neural tissues and may play a general role in cell-cell communication via signaling from its intracellular domain to the actin cytoskeleton during directional cell migration. Allelic variants of this gene have been associated with autism^[3] and addiction vulnerability. Alternative splicing results in multiple transcript variants encoding different isoforms.^[2]
