Myelin protein zero 's extracellular domain binds to the myelin sphingolipid membrane .
Myelin protein zero 's extracellular domain holds together myelin layers using homotypic interactions with other myelin protein zero extracellular domains , and with extracellular tryptophan residues interacting with the membrane .
