| molecularNote | A lentiviral transgenic approach was used to generate these mice. The SB-sa-IRES-rtTA-pA-SB-Tyro-WPRE-FUGW lentiposon transgene (LV2223) was designed with a Sleeping Beauty (SB) transposon (containing a slice-acceptor::IRES::rtTA::polyA gene trap), a mouse tyrosinase minigene (Tyro), and a woodchuck hepatitis virus post-transcriptional regulatory element (WPRE) in the FUGW self-inactivating HIV-based lentiviral vector backbone. The SB transposon and Tyro minigene replaced the ubiquitin-c promoter and EGFP sequences originally found in the FUGW lentiviral vector. The 1200 bp SB transposon used in this transgene has an inverted repeat/direct repeat sequence (IR/DR; the SB transposon recognition site), an adenovirus splice acceptor, a stop sequence (3xSTOP), an internal ribosome entry site (IRES; from human X-chromosome-linked inhibitor of apoptosis (XIAP)), a sequence encoding a-n optimized form of reverse tetracycline controlled transactivator (rtTA2S; with stop codon), a human growth hormone polyA sequence, and a second IR/DR sequence. The IR/DR sequences are outward-facing (pointed away from the sa-IRES-rtTA-pA). The Tyro minigene is composed of the mouse Tyr enhancer region (623 bp), promoter region (657 bp), and 1566 bp cDNA sequence (including the stop codon); all in sense orientation relative to the FUGW backbone. There is no polyA site between the Tyro minigene and WPRE sequence. The WPRE sequence functions to enhance the mRNA transcript stability. In line OVE2489A, a single copy of the lentiposon inserted into intron 64 [NCBI37/mm9; 3'-111,898,386(-)] in the sense orientation. |
