Figure 8. Model of Cdk5-phosphorylated CASK at the presynaptic terminal.

Figure 8

Non-phosphorylated CASK is trafficked to and within the presynaptic terminal by liprin-α proteins, where Cdk5-dependent phosphorylation then dissociates CASK from the complex. CASK is then available to interact with the presynaptic machinery, such as Neurexins, SynCAM, Mint1, Veli and voltage-gated calcium channels.
