Abstract
Yuniati et al. perform a proteomic screen to identify E3 substrates that are ubiquitylated at cellular membranes and find that the ER-shaping protein Lunapark is ubiquitylated by the CRL3KLHL12 ubiquitin ligase. They show that Lunapark binds mTORC1 and affects its activity, and defects in Lunapark ubiquitylation lead to neurodevelopmental defects.
