However, understanding of the underlying pathomechanisms is lacking. Recently, mutations in\n                    <jats:italic>KBTBD13<\/jats:italic>\n                    ,\n                    <jats:italic>KLHL40,<\/jats:italic>\n                    and\n                    <jats:italic>KLHL41<\/jats:italic>\n                    , three substrate adaptors for the E3 ubiquitin ligase Cullin-3, have been associated with early-onset nemaline myopathies. We hypothesized that deregulation of Cullin-3 and its muscle protein substrates may be responsible for disease development. Using\n                    <jats:italic>Cullin-3<\/jats:italic>\n                    \u2013knockout mice, we identified accumulation of non-muscle \u03b1-actinins (ACTN1 and ACTN4) in muscles of these mice, which we also observed in patients with mutations in\n                    <jats:italic>KBTBD13<\/jats:italic>\n                    . Our data reveal that proper regulation of Cullin-3 activity and ACTN1 levels is essential for normal muscle and neuromuscular junction development. While ACTN1 is naturally downregulated during myogenesis, its overexpression in C2C12 myoblasts triggered defects in fusion, myogenesis, and acetylcholine receptor clustering \u2014 features that we characterized in Cullin-3\u2013deficient mice. Taken together, our data highlight the importance of Cullin-3\u2013mediated degradation of ACTN1 for muscle development, and indicate what is to our knowledge new pathomechanism for the etiology of myopathies seen in Cullin-3\u2013knockout mice and patients with nemaline myopathy.\n                  <\/jats:p>","DOI":"10.1172\/jci.insight.125665","type":"journal-article","created":{"date-parts":[[2019,4,16]],"date-time":"2019-04-16T12:01:55Z","timestamp":1555416115000},"source":"Crossref","is-referenced-by-count":24,"title":["Cullin-3\u2013dependent deregulation of ACTN1 represents a pathogenic mechanism in nemaline myopathy"],"prefix":"10.1172","volume":"4","author":[{"given":"Jordan","family":"Blondelle","sequence":"first","affiliation":[{"name":"Division of Cardiology, School of Medicine, UCSD, La Jolla, California, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kavya","family":"Tallapaka","sequence":"additional","affiliation":[{"name":"Division of Cardiology, School of Medicine, UCSD, La Jolla, California, USA."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2864-6199","authenticated-orcid":true,"given":"Jane T.","family":"Seto","sequence":"additional","affiliation":[{"name":"Neuromuscular Research, Murdoch Children\u2019s Research Institute, Royal Children\u2019s Hospital, Parkville, Victoria, Australia."},{"name":"Department of Paediatrics, University of Melbourne, Parkville, Victoria, Australia."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Majid","family":"Ghassemian","sequence":"additional","affiliation":[{"name":"Department of Chemistry and Biochemistry.
