Abstract: Since the resurrection of Sleeping Beauty(SB11), piggyBac(PB) is also described to work in mammals. DNA transposons are mobile genetic units identified in many mammals, can change the structures of genome and influence the function of special gene. The exogenous gene can be inserted into a new locus by transposase following a 'cut and paste' mechanism, so transposons have been widely used as tools to study the gene function, generate transgenic animals, and research gene therapy. Compared with SB11, PB has higher transposition level, no dose inhibition effect, and can carry larger fragments, thus PB has been cared more and more recently. Herein, we describe its mechanism of action,the factors influencing the transgenic effects,and the application in mammals.

Key words: piggyBac; transposon; transgene
