Query: Convergent evolution of genome guardian functions in a parasite-specific p53 homolog SignificanceP53 is a widely studied tumor suppressor that is found throughout metazoans, including invertebrates that do not develop malignancies. The prevailing theory for why this is the case is that P53 originally evolved to protect the germline of early metazoans from genotoxic stress such as UV radiation. In this study, we examine the function of two P53 homologs in the parasitic flatworm Schistosoma mansoni. The first is orthologous to canonical P53, and regulates stem cell maintenance and differentiation. The second P53 gene is a parasite-specific paralog that is required for the normal response to genotoxic stress. This implies that the ability to respond to genotoxic stress in parasitic flatworms may have arisen from convergent evolution.
