Here, we show that CDKL5 binds to the scaffolding protein postsynaptic density (PSD)-95, and that this binding promotes the targeting of CDKL5 to excitatory synapses. Interestingly, this binding is not constitutive, but governed by palmitate cycling on PSD-95. Furthermore, pathogenic mutations that truncate the C-terminal tail of CDKL5 diminish its binding to PSD-95 and synaptic accumulation. Importantly, down-regulation of CDKL5 by RNA interference (RNAi) or interference with the CDKL5\u2013PSD-95 interaction inhibits dendritic spine formation and growth. These results demonstrate a critical role of the palmitoylation-dependent CDKL5\u2013PSD-95 interaction in localizing CDKL5 to synapses for normal spine development and suggest that disruption of this interaction by pathogenic mutations may be implicated in the pathogenesis of CDKL5-related disorders.\n                  <\/jats:p>","DOI":"10.1073\/pnas.1300003110","type":"journal-article","created":{"date-parts":[[2013,5,14]],"date-time":"2013-05-14T00:55:35Z","timestamp":1368492935000},"page":"9118-9123","update-policy":"https:\/\/doi.org\/10.1073\/pnas.cm10313","source":"Crossref","is-referenced-by-count":106,"title":["Palmitoylation-dependent CDKL5\u2013PSD-95 interaction regulates synaptic targeting of CDKL5 and dendritic spine development"],"prefix":"10.1073","volume":"110","author":[{"given":"Yong-Chuan","family":"Zhu","sequence":"first","affiliation":[{"name":"Institute of Neuroscience and State Key Laboratory of Neuroscience, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dan","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Neuroscience and State Key Laboratory of Neuroscience, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Wang","sequence":"additional","affiliation":[{"name":"Institute of Neuroscience and State Key Laboratory of Neuroscience, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bin","family":"Lu","sequence":"additional","affiliation":[{"name":"Institute of Neuroscience and State Key Laboratory of Neuroscience, and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Zheng","sequence":"additional","affiliation":[{"name":"School of Pharmacy, East China University of Science and Technology, Shanghai 200237, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shi-Lin","family":"Zhao","sequence":"additional","affiliation":[{"name":"Key Laboratory of Systems Biology, Institute of Biochemistry and Cell Biology, Shanghai Institutes for Biological Sciences, Chinese Academy of Sciences, Shanghai 200031, China;
