Abstract	Cabbage butterflies, Pieris rapae and Pieris brassicae, contain strong cytotoxic proteins, designated as pierisin-1 and -2, against cancer cell lines. These proteins exhibit DNA ADP-ribosylating activity. To determine the distribution of substances with cytotoxicity and DNA ADP-ribosylating activity among other species, crude extracts from 20 species of the family Pieridae were examined for cytotoxicity in HeLa cells and DNA ADP-ribosylating activity. Both activities were detected in extracts from 13 species: subtribes Pierina (Pieris rapae, Pieris canidia, Pieris napi, Pieris melete, Pieris brassicae, Pontia daplidice, and Talbotia naganum), Aporiina (Aporia gigantea, Aporia crataegi, Aporia hippia, and Delias pasithoe), and Appiadina (Appias nero and Appias paulina). All of these extracts contained substances recognized by anti-pierisin-1 antibodies, with a molecular mass of approximately 100 kDa established earlier for pierisin-1. Moreover, sequences containing NAD-binding sites, conserved in ADP-ribosyltransferases, were amplified from genomic DNA from 13 species of butterflies with cytotoxicity and DNA ADP-ribosylating activity by PCR. Extracts from seven species, Appias lyncida, Leptosia nina, Anthocharis scolymus, Eurema hecabe, Catopsilia pomona, Catopsilia scylla, and Colias erate, showed neither cytotoxicity nor DNA ADP-ribosylating activity, and did not contain substances recognized by anti-pierisin-1 antibodies. Sequences containing NAD-binding sites were not amplified from genomic DNA from these seven species. Thus, pierisin-like proteins, showing cytotoxicity and DNA ADP-ribosylating activity, are suggested to be present in the extracts from butterflies not only among the subtribe Pierina, but also among the subtribes Aporiina and Appiadina. These findings offer insight to understanding the nature of DNA ADP-ribosylating activity in the butterfly.
