Physical and functional interaction between A20 and ATG16L1-WD40 domain in the control of intestinal homeostasis

Abstract

Maintaining the intestinal barrier function requires a balance of multiple signalling pathways. Here the authors show that A20, an anti-inflammatory and anti-apoptotic protein, and Atg1611, an autophagy regulator, cross-regulate their respective protein levels and function to serve compensatory and redundant roles in fine-tuning gut barrier homeostasis.
