To gain insights into the regulation of autophagy, we recently conducted a genome-wide CRISPR-Cas9 knockout screen using cells expressing endogenous LC3B tagged with GFP-mCherry as a reporter. This approach allowed us to identify the ubiquitin-activating enzyme UBA6 and the hybrid ubiquitin-conjugating enzyme/ubiquitin ligase BIRC6 as novel autophagy regulators. We found that these enzymes cooperate to mediate monoubiquitination and proteasomal degradation of LC3B, thus limiting the pool of LC3B available for autophagy. Depletion of UBA6 or BIRC6 increased the level of cytosolic LC3B, enhancing the degradation of autophagy adaptors and the clearance of intracellular proteins aggregates. This finding could be the basis for the development of pharmacological inhibitors of UBA6 or BIRC6 for the treatment of protein aggregation disorders. Recent work by another group showed that BIRC6 itself is subject to ubiquitination and proteasomal degradation, highlighting the existence of a complex regulatory network for the control of LC3B levels."xsd:string |
