L1

(= NgCAM)

Neural adhesion molecule with 6 immunoglobulin-type C2 domains and fibronectin type III repeats, making it another member of the immunoglobulin superfamily with binding domains similar to fibronectin. The purified molecule, immobilizd on a culture dish, is a potent substrate for neurite outgrowth. See also neuroglian and NCAM.
