Whereas TRAF6 was dispensable for pancreatic β cell function at baseline, TRAF6 was pivotal for insulin secretion, mitochondrial respiration, and mitophagy following metabolic stress in mouse and human islets. TRAF6 was critical for the recruitment and function of the ubiquitin-mediated (Parkin-dependent) mitophagy machinery.
