TAK1 is an essential kinase for STING trafficking


ABSTRACT: STING-mediated activation of TAK1 at the ER, which in turn induces STING phosphorylation and initiates STEEP-mediated STING trafficking. These findings shed light on an early signaling event in the regulation of STING exit from ER.

The translocation of stimulator of interferon genes (STING) from the endoplasmic reticulum (ER) to the ER-Golgi intermediate compartment (ERGIC) enables its activation. However, the mechanism underlying the regulation of STING exit from the ER remains elusive. Here, we found that STING induces the activation of transforming growth factor beta-activated kinase 1 (TAK1) prior to STING trafficking in a TAK1 binding protein 1 (TAB1)-dependent manner. Intriguingly, activated TAK1 directly mediates ST  ...[more]
