UniProtKB description:  ADP-ribosylates double-stranded DNA by targeting the N2 amino group of dG residues; 10-fold less active on tRNA. Induces apoptosis in a range of human cell lines (PubMed:10485873, PubMed:11592983). May play a role in removing unnecessary or harmful cells during pupation (PubMed:15528160) (Probable). May play a role in defense against parasitic wasps; its habitual predator Cotesia glomerata is only susceptible after removal of its eggshell or the surface of the larval caudal vesicle, while other wasps are damaged by this protein (PubMed:23637752) (Probable). The wild-type catalytic domain (residues 1-233) cannot be expressed in E.coli as it is unstable probably due to its toxicity. A catalytic domain fragment (Glu-165 mutated to Gln) binds dsDNA but not ssDNA; the presence of the linker inhibits DNA-binding (PubMed:28765284).
