| Post Translational Modifications | Ubiquitinated. Phosphorylation at Ser-56 by CHEK2 under oxidative stress, activates the E3 ligase activity and promotes ATG7 ubiquitination leading to positive regulation of the autophagosme assembly. |
| Function | E3 ubiquitin ligase that plays a role in various biological processes including neural stem cell differentiation, innate immunity, inflammatory resonse and autophagy. Plays a role in virus-triggered induction of IFN-beta and TNF-alpha by mediating the ubiquitination of STING1. Mechanistically, targets STING1 for 'Lys-63'-linked ubiquitination which promotes the interaction of STING1 with TBK1. Regulates bacterial clearance and promotes autophagy in Mycobacterium tuberculosis-infected macrophages. Negatively regulates TLR3/4-mediated innate immune and inflammatory response by triggering the autophagic degradation of TICAM1 in an E3 activity-independent manner. Plays an essential role in oxidative stress induced cell death by inducing loss of transmembrane potential and enhancing mitochondrial reactive oxygen species (ROS) production during oxidative stress conditions. Ubiquitinates XIAP and targets it for proteasomal degradation. Ubiquitinates DTNBP1 (dysbindin) and promotes its degradation. May ubiquitinate BBS2. Ubiquitinates PIAS4/PIASY and promotes its degradation in keratinocytes treated with UVB and TNF-alpha. Also acts as a regulator of autophagy by mediating formation of unanchored 'Lys-63'-linked polyubiquitin chains that activate ULK1: interaction with AMBRA1 is required for ULK1 activation. Positively regulates dendritic branching by promoting ubiquitination and subsequent degradation of the epigenetic factor CDYL. Under metabolic stress and phosphorylation by CHK2, mediates 'Lys-63'-linked ubiquitination of ATG7 at 'Lys-41' to initiate autophagy. |
