The quest for targeted therapies is critical in the battle against cancer. The RAS/ MAP kinase pathway is frequently implicated in neoplasia, with ERK playing a crucial role as the most distal kinase in the RAS signaling cascade. Our previous research demonstrated that the interaction between ERK and MYD88, an adaptor protein in innate immunity, is crucial for RAS-dependent transforma- tion and cancer cell survival. In this study, we examine the biological con- sequences of disrupting the ERK-MYD88 interaction through the ERK D-recruitment site (DRS), while preserving ERK ' s kinase activity. Our results indicate that EI-52, a small-molecule benzimidazole targeting ERK-MYD88 interaction induces an HRI-mediated integrated stress response (ISR), resulting in immunogenic apoptosis speci fi c to cancer cells. Additionally, EI-52 exhibits anti-tumor ef fi cacy in patient-derived tumors and induces an anti-tumor T cell response in mice in vivo. These fi ndings suggest that inhibiting the ERK-MYD88 interaction may be a promising therapeutic approach in cancer treatment.
