CUL7 E3 Ubiquitin Ligase Mediates the Degradation of Activation-Induced Cytidine Deaminase and Regulates the Ig Class Switch Recombination in B Lymphocytes

15 May 2019

Abstract excerpt

Abstract Activation-induced cytidine deaminase (AID) initiates class switch recombination and somatic hypermutation in Ig genes. The activity and protein levels of AID are tightly controlled by various mechanisms. In this study, we found that CUL7 E3 ubiquitin ligases specifically mediated AID ubiquitination. CUL7 overexpression or knockdown influenced the decay of AID, affecting AID protein levels and...
