Outline of Final Research Achievements |
We showed that glutamate receptor GluRδ2 triggers cerebellar synapse formation by clustering four neurexins through trans-synaptic interaction. In the cerebrum, IL1-receptor accessory protein-like 1 (IL1RAPL1) responsible for intellectual disability and autism spectrum disorder induces spine formation of cortical neurons through Mcf2l-RhoA-ROCK signaling. We found that in addition to IL1RAPL1, IL-1RAcP also mediates synapse formation of cortical neurons through interaction with presynaptic PTPδ. Furthermore, by analyzing the structure of crystalized PTPδ-IL1RAPL1 complex, we showed that mini-exon peptides inserted into immunoglobulin-like domains of PTPδ play critical roles in the interaction with IL1RAPL1.
