Figure 19-31The cell adhesion protein N-CAM

(A) Four forms of N-CAM. The extracellular part of the polypeptide chain in each case is folded into five Ig-like domains (and one or two other domains called fibronectin type III repeats). Disulfide bonds (red) connect the ends of each loop that forms an Ig-like domain. (B) A model for the homophilic interaction that allows N-CAM to mediate cell-cell adhesion.
