Protein turnover downstream of the Nipbl/CRL4 axis contributes to abnormal development in zebrafish embryos

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Mutations in cohesins cause cohesinopathies such as Cornelia de Lange Syndrome (CdLS) and Roberts Syndrome (RBS). Prior findings demonstrate that Esco2 (a cohesin activator) and Smc3 (a core cohesin subunit) regulate the CRL4 E3 ubiquitin ligase. SMC3 mutations, however, account for a small percentage of CdLS.
