The following standardised nomenclature for the 3 genes which encode prophenoloxidases in D. melanogaster was suggested by Bruno Lemaitre and agreed by Erjun Ling. Current symbol New symbol New name CG number proPO-A1 PPO1 Prophenoloxidase 1 CG42639 proPO45 PPO2 Prophenoloxidase 2 CG8193 proPO59 PPO3 Prophenoloxidase 3 CG42640 Note that the 1/ 2/ 3 suffixes used in this standardised nomenclature are unrelated to the "A1" "A2" "A3" nomenclature originally described in Mitchell and Weber, 1965, Science 148: 964--965 (FBrf0017315).
