Autophagy acts through TRAF3 and RELB to regulate gene expression via antagonism of SMAD proteins

Abstract

Macroautophagy can regulate cell signalling and tumorigenesis but the molecular mechanisms are unclear. Here the authors show selective degradation of the signalling scaffold TRAF3 by autophagy and consequent activation of the NF-κB family member RELB regulate gene expression via antagonism of SMAD proteins.
