E3 ubiquitin ligase that plays an essential role in the organization of autophagic response and ubiquitination upon lysosomal and phagosomal damages. Plays a role in the stress-induced biogenesis and degradation of protein aggresomes by regulating the p62-KEAP1-NRF2 signaling and particularly by modulating the ubiquitination levels and thus stability of NRF2. Acts as a scaffold protein and facilitates autophagic degradation of protein aggregates by interacting with p62/SQSTM, ATG16L1 and LC3B/MAP1LC3B. In turn, protects the cell against oxidative stress-induced cell death as a consequence of endomembrane damage. S-ubiquitinyl-[E2 ubiquitin-conjugating enzyme]-L-cysteine + [acceptor protein]-L-lysine = [E2 ubiquitin-conjugating enzyme]-L-cysteine + N(6)-ubiquitinyl-[acceptor protein]-L-lysine. Homodimerizes via its coiled-coil domain. Heterodimerizes with MID1, TRIM24 and PML. Interacts with Galectin-3/LGALS3 in a ULK1-dependent manner; this interaction mediates autophagy of damage endomembranes. Interacts with BECN1. Interacts with ATG16L1. Interacts with p62/SQSTM and LC3B/MAP1LC3B. Widely expressed. Expressed in basal keratinocytes. Phosphorylated by ULK1. Auto-ubiquitinates via its B-Boxes. Belongs to the TRIM/RBCC family.
