Predicted to enable chromatin binding activity; histone binding activity; and poly-ADP-D-ribose binding activity. Predicted to be involved in double-strand break repair; peptidyl-serine ADP-ribosylation; and regulation of protein modification process. Predicted to act upstream of or within DNA repair. Predicted to be located in chromatin and site of DNA damage. Predicted to be active in nucleus. Orthologous to human HPF1 (histone PARylation factor 1).
