品系来源:The Sleeping Beauty transposon construct, T2/Bart3 consists of inverted terminal repeats separated by a gene trap cassette. The gene trap cassette consists of two splice acceptors, one from adenovirus and one from the mouse Hox9a gene, situated in opposite orientations. Each splice acceptor is followed by stop codons in each reading frame and a polyadenylation signal. Furthermore, the T2/Bart3 transposon harbors a mouse tyrosinase minigene which rescues the phenotype of albino rats, but demonstrates position effect variegated expression.
