Binding of ankyrins is dependent on the phosphorylation and dephosphorylation state of the tyrosine in the L1 FIGQY motif. In the dephosphorylated state ankyrins bind to L1 and in the phosphorylated state L1 releases from ankyrins and binds to doublecortin.
The specific kinase that is responsible for the phosphorylation of this tyrosine residue is still unknown, but components of the MAP kinase pathway may regulate this event. Tyrosine phosphorylation abolishes ankyrin binding and also increases L1 lateral mobility and neurite growth
