Orchestrated apoptosis in planarian Dugesia japonica is very important for its degrowth and regeneration. Apoptosis Inhibitor-5 (API5) is an anti-apoptotic factor that negatively regulates cell apoptosis. We characterized the conserved structure of DjApi5, however, the biological function of DjApi5 in planarians needs further investigation. In this study, we found that DjApi5 and its interacting molecular DjAcinus are required for planarian homeostasis, which may be correlated with their specific localization in neoblasts in addition to their anti-apoptosis functions. We further demonstrated the increased expression of DjApi5 during planarian regeneration, and DjApi5 deficiency affects normal regeneration processes. These results indicated new functions of DjApi5 in development.
