异体自噬是选择性自噬的一种形式,涉及通过多种识别、招募和泛素化事件来靶向和消除细胞内病原体。 E3 泛素连接酶控制泛素化级联中的底物选择性;然而,一直缺乏系统方法来绘制 E3 连接酶在抗菌自噬中的作用。在这里,我们筛选了 600 多种假定的人类 E3 连接酶,鉴定了接头蛋白招募和 LC3 细菌共定位(抗菌自噬的关键步骤)所需的 E3 连接酶。一种公正的信息学方法将 RNF166 确定为与自噬网络相互作用并控制泛素以及自噬接头 p62 和 NDP52 向细菌招募的关键基因。机理研究表明,RNF166 催化 p62 残基 K91 和 K189 处的 K29 和 K33 连接多泛素化。因此,我们的研究扩展了介导抗菌自噬的 E3 连接酶的目录,并确定了 RNF166 在此过程中的关键作用。
Xenophagy is a form of selective autophagy that involves the targeting and elimination of intracellular pathogens through several recognition, recruitment, and ubiquitination events. E3 ubiquitin ligases control substrate selectivity in the ubiquitination cascade; however, systematic approaches to map the role of E3 ligases in antibacterial autophagy have been lacking. Here we screened more than 600 putative human E3 ligases, identifying E3 ligases that are required for adaptor protein recruitment and LC3-bacteria colocalization, critical steps in antibacterial autophagy. An unbiased informatics approach pinpointed RNF166 as a key gene that interacts with the autophagy network and controls the recruitment of ubiquitin as well as the autophagy adaptors p62 and NDP52 to bacteria. Mechanistic studies demonstrated that RNF166 catalyzes K29- and K33-linked polyubiquitination of p62 at residues K91 and K189. Thus, our study expands the catalog of E3 ligases that mediate antibacterial autophagy and identifies a critical role for RNF166 in this process.
