Interaction with ERM may lead to lateral oligomerization of phosphorylated L1 and this enhances the homophilic trans adhesion of L1.
L1 mediates cell-cell adhesion by a trans-homophilic binding mechanism. In the nonengaged resting state the L1 N-terminal Ig domains adopt a horseshoe like structure due to an intramolecular binding between domains 1 and 4 or 2 and 3, respectively. When engaged in homophilic binding between adjacent cells, L1 could undergo a conformational change leading to a pairwise antiparallel alignment of Ig domains 1-4 and 2-3.
