| 摘 要： | piggyBac（PB）转座系统来源于昆虫鳞翅目,属于真核生物的第二类转座系统,主要采取＂剪切粘帖＂机制发生转座。PB系统转座效率高,宿主范围广,广泛应用于昆虫等低等生物的基因转移及突变筛选。近年来,研究发现PB系统在哺乳动物及其细胞中也具有高效的转座活性,已在动物基因组功能研究、基因转移及诱导多能干细胞等领域得到了广泛应用。本文就PB系统近年来在哺乳动物及其细胞中的研究进展、应用前景及存在问题进行了综述。

| Abstract: | piggyBac(PB) transposon,a TTAA-specific transposon firstly isolated from the genome of cabbage looper moth,is a member of class II transposon family,which jumps via a cut and paste mechanism.PB transposon has been widely used for insertion mutagenesis and carrying gene in lower organism.Recent studies demonstrate that PB transposon system possesses high activity of delivering large pieces of DNA in mammals and cultured mammalian cells and can remobilize efficiently without any track.These new findings accel... |
