    The extracellular domain of NCAM consists of five immunoglobulin-like (Ig) domains followed by two fibronectin type III (FNIII) domains. The different domains of NCAM have been shown to have different roles with the Ig domains being involved in homophilic binding to NCAM, and the FNIII domains being involved signalling leading to neurite outgrowth.
