PiggyBac Transposable Element Derived 5 is an enzyme that in humans is encoded by the PGBD5gene.[1] PGBD5 is a DNA transposase related to the ancient PiggyBac transposase first identified in the cabbage looper moth, Trichoplusia ni.[2] The gene is believed to have been domesticated over 500 million years ago in the common ancestor of cephalochordates and vertebrates.[3] Although the catalytic triad of the protein composed of three aspartic acid residues is not conserved through evolution,[3] the protein has been shown to be able to transpose DNA in a sequence-specific, cut-and-paste fashion.[4]
