One couples ubiquitin-like Atg8 to phosphatidylethanolamine, and the other couples ubiquitin-like Atg12 to Atg5. Atg12 similar to Atg5 then forms a heterodimer with Atg16. Membrane recruitment of the Atg12 similar to Atg5/Atg16 complex defines the Atg8 lipidation site. Lipidation requires a PI3P-containing precursor. How PI3P is sensed and used to coordinate the conjugation systems remained unclear. Here, we show that Atg21, a WD40 beta-propeller, binds via PI3P to the preautophagosomal structure (PAS). Atg21 directly interacts with the coiled-coil domain of Atg16 and with Atg8. This latter interaction requires the conserved F5K6-motif in the N-terminal helical domain of Atg8, but not its AIM-binding site. Accordingly, the Atg8 AIM-binding site remains free to mediate interaction with its E2 enzyme Atg3. Atg21 thus defines PI3P-dependently the lipidation site by linking and organising the E3 ligase complex and Atg8 at the PAS."],["dc.identifier.doi","10.15252/embj.201488957"],["dc.identifier.isi","000352167300012"],["dc.identifier.pmid","25691244"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/37507"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Wiley-blackwell"],["dc.relation.issn","1460-2075"],["dc.relation.issn","0261-4189"],["dc.title","PI3P binding by Atg21 organises Atg8 lipidation"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

This process is considered to remove damaged, superfluous and aged organelles. However, little is known about how defective organelles are recognized, what types of damage induce turnover, and whether an identical set of factors contributes to degradation under different conditions. Here we systematically compared the mitophagy rate and requirement for mitophagy-specific proteins during post-log-phase and rapamycin-induced mitophagy. To specifically assess mitophagy of damaged mitochondria, we analyzed cells accumulating proteins prone to degradation due to lack of the mitochondrial AAA-protease Yme1. While autophagy 32 (Atg32) was required under all tested conditions, the function of Atg33 could be partially bypassed in post-log-phase and rapamycin-induced mitophagy. Unexpectedly, we found that Uth1 was dispensable for mitophagy. A re-evaluation of its mitochondrial localization revealed that Uth1 is a protein of the inner mitochondrial membrane that is targeted by a cleavable N-terminal pre-sequence. In agreement with our functional analyses, this finding excludes a role of Uth1 as a mitochondrial surface receptor."],["dc.identifier.doi","10.1111/febs.12468"],["dc.identifier.gro","3142274"],["dc.identifier.isi","000327132100006"],["dc.identifier.pmid","23910823"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/6465"],["dc.language.iso","en"],["dc.notes.intern","WoS Import 2017-03-10"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.eissn","1742-4658"],["dc.relation.issn","1742-464X"],["dc.title","Uth1 is a mitochondrial inner membrane protein dispensable for post-log-phase and rapamycin-induced mitophagy"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.subtype","original"],["dspace.entity.type","Publication"]]
