Although the accurate targeting of myelin to axons and its maintenance are critical for CNS performance, the molecular pathways that regulate these processes remain poorly understood. Through a combination of zebrafish genetics, mouse models, and primary OL cultures, we found FBXW7, a recognition subunit of an E3 ubiquitin ligase complex, is a regulator of adult myelination in the CNS. Loss of\n                  <jats:italic>Fbxw7<\/jats:italic>\n                  in myelinating OLs resulted in increased myelin sheath lengths with no change in myelin thickness. As the animals aged, they developed progressive abnormalities including myelin outfolds, disrupted paranodal organization, and ectopic ensheathment of neuronal cell bodies with myelin. Through biochemical studies we found that FBXW7 directly binds and degrades the N-terminal of Myelin Regulatory Factor (N-MYRF), to control the balance between oligodendrocyte myelin growth and homeostasis.\n                <\/jats:p>","DOI":"10.1101\/2024.10.15.618515","type":"posted-content","created":{"date-parts":[[2024,10,18]],"date-time":"2024-10-18T05:53:12Z","timestamp":1729230792000},"source":"Crossref","is-referenced-by-count":4,"title":["FBXW7 regulates MYRF levels to control myelin capacity and homeostasis in the adult CNS"],"prefix":"10.64898","author":[{"given":"Hannah Y.","family":"Collins","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryan A.","family":"Doan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaxing","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason E.","family":"Early","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Megan E.","family":"Madden","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tyrell","family":"Simkins","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David A.","family":"Lyons","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kelly R.","family":"Monk","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ben","family":"Emery","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2024102204051530000_2024.10.15.618515v1.1","doi-asserted-by":"publisher","DOI":"10.1038\/238217a0"},{"key":"2024102204051530000_2024.10.15.618515v1.2","doi-asserted-by":"publisher","DOI":"10.1007\/978-1-4757-1830-0_4"},{"key":"2024102204051530000_2024.10.15.618515v1.3","doi-asserted-by":"publisher","DOI":"10.1146\/annurev.neuro.30.051606.094309"},{"key":"2024102204051530000_2024.10.15.618515v1.4","doi-asserted-by":"publisher","DOI":"10.1113\/jphysiol.1951.sp004545"},{"key":"2024102204051530000_2024.10.15.618515v1.5","doi-asserted-by":"publisher","DOI":"10.1016\/j.devcel.2013.05.013"},{"key":"2024102204051530000_2024.10.15.618515v1.6","doi-asserted-by":"publisher","DOI":"10.1016\/S0896-6273(01)00414-7"},{"key":"2024102204051530000_2024.10.15.618515v1.7","doi-asserted-by":"publisher","DOI":"10.1038\/nn.3390"},{"key":"2024102204051530000_2024.10.15.618515v1.8","doi-asserted-by":"publisher","DOI":"10.1038\/s41593-018-0121-5"},{"key":"2024102204051530000_2024.10.15.618515v1.9","doi-asserted-by":"publisher","DOI":"10.1038\/nn1426"},{"key":"2024102204051530000_2024.10.15.618515v1.10","doi-asserted-by":"publisher","DOI":"10.1016\/j.devcel.2015.05.013"},{"key":"2024102204051530000_2024.10.15.618515v1.11","doi-asserted-by":"publisher","DOI":"10.1016\/j.devcel.2015.06.011"},{"key":"2024102204051530000_2024.10.15.618515v1.12","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.4178-07.2008"},{"key":"2024102204051530000_2024.10.15.618515v1.13","doi-asserted-by":"publisher","DOI":"10.1016\/j.cell.2009.04.031"},{"key":"2024102204051530000_2024.10.15.618515v1.14","doi-asserted-by":"publisher","DOI":"10.1523\/JNEUROSCI.1069-12.2012"},{"key":"2024102204051530000_2024.10.15.618515v1.15","doi-asserted-by":"publisher","DOI":"10.1016\/j.tins.2019.01.002"},{"key":"2024102204051530000_2024.10.15.618515v1.16","doi-asserted-by":"publisher","DOI":"10.1126\/science.aaf6463"},{"key":"2024102204051530000_2024.10.15.618515v1.17","doi-asserted-by":"crossref","unstructured":"Yeung, M. et al.
