PiggyBac izvedeni prenosivi element 5 jest enzim koji je kod ljudi kodiran genom PGBD5 sa hromosoma 1 .[ 1] PiggyBac transposaza prci puta identificurana je kod kupudnog moljca, Trichoplusia ni .[ 2] zajedničkog pretka glavonožaca i kičmenjaka .[ 3]
Dužina polipeptidnog lanca je 455 aminokiselina , a molekulska težina 51.642Da .[ 4]

Pretpostavljena katalitska trijada proteina sastavljenog od tri asparaginskokiselinska ostatka, tokom evolucije, konzervirana je među genima sličnim PGBD5,[ 5] [ 3] [ 5] DNK , specifičnih za mjesto u ljudskim tumorima .[ 6]
Ljudski PGBD5 može mobilizirati transpozone insekata PiggyBac u kulturi ljudskih ćelija.[ 7]
U moždanom tkivu zrelih miševa, PGBD5 se nalazi prvenstveno u regijama olfaktornog bulbusa , hipokampusu i cerebelumu . U moždanom tkiva mišjih embriona , PGBD5 se nalazi ne samo u medijalnom paliju i pretponsnom istmusu, koji su područja mozga koja se razvojijaju u hipokampus i mali mozak već i u područjima u embrionskom dijelu mozga koji stvara hipotalamus i medulu u korteksnom tkivu.
PGBD5 je eksprimiran u većini dječijih solidnih tumora.[ 8] Ekspresija gena pojačana je kod sporadične Creutzfeldt-Jakobove bolesti.[ 9] neuronima , zatim oliodendrocitima , zrelim astrocitima , fetusnim astrocitima, endotelnim ćelijama i potom u mikroglijama/makrofagima .[ 10]
