An optimized protocol to detect protein ubiquitination and activation by ubiquitination assay in vivo and CCK-8 assay

Summary: E3 ubiquitin ligases play a role in protein degradation, cellular localization, and activation, and their dysregulation is associated with human diseases. Here, we present a protocol to detect IGF2BP1 ubiquitination and activation by an E3 ubiquitin ligase FBXO45. We describe steps for prep...

description Summary: E3 ubiquitin ligases play a role in protein degradation, cellular localization, and activation, and their dysregulation is associated with human diseases. Here, we present a protocol to detect IGF2BP1 ubiquitination and activation by an E3 ubiquitin ligase FBXO45. We describe steps for preparing cells and transfecting plasmids. We detail the use of western blot to detect IGF2BP1 ubiquitination and a Cell Counting Kit-8 (CCK-8) assay to detect IGF2BP1 activation. This protocol is applicable to other proteins of interest.For complete details on the use and execution of this protocol, please refer to Lin et al. (2021).1 : Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
