Figure 4: Activation and signaling by the Ripoptosome and its regulation by c-FLIP isoforms. Cellular stress and IAPs proteasomal degradation after treating cells with IAP antagonists triggers formation of the Ripoptosome, a complex of active RIP1, FADD, caspase-8/10, and c-FLIP isoforms). Its formation is independent of the mitochondrial and death receptor pathways. c-FLIPL inhibits. |
