| Outline of Final Research Achievements |
The Cyclin-dependent kinase-like 5 (CDKL5) gene encodes for a serine-threonine kinase sharing homology to Mitogen-activated kinases (MAPKs) and Cyclin-dependent kinases (CDKs). Recently, mutations in the CDKL5 gene have been identified in the patients with neurodevelopmental disorders associated with intractable epilepsies. However, neither its molecular functions or pathomechanisms caused by its mutations are largely unknown. Aiming to elucidate these problems, I have taken multidimensional strategies, combining an unbiased interactome approach and a targeted loss-of-function (LOF) approach. For the LOF approach, we have generated the Cdkl5 knockout mouse and identified various neurological abnormalities. For the interactome approach, we performed the yeast two-hybrid screening and proteomic screening, and identified several CDKL5 interacting proteins. The combination of these approaches suggested possible mechanisms of CDKL5 regulating neural functions during development.
