XIE62-1004 is a chemical compound that induces the interaction between p62 and LC3 by binding to the ZZ domain of p62. This interaction promotes p62 self-aggregation and its subsequent interaction with LC3 on autophagosome membranes, thereby facilitating the delivery of cargo proteins to the autophagosome for degradation. XIE62-1004 is effective both in vitro and in vivo, displaying specificity for the wild type of p62 and exhibiting its actions in a concentration- and time-dependent manner. Additionally, it induces the degradation of mutant huntingtin in vitro and can be employed in AUTAC protein degradation systems to trigger autophagy via p62 self-aggregation and LC3 interaction.
