Mutation description

• Allele Type: Targeted (Conditional ready, Inducible, Reporter, Transactivator)
• Inducer: doxycycline/tetracycline
• Mutation: Insertion
• Mutation details: The vector is designed with (from 5' to 3') an FRT3 site, two copies of chicken beta-globin HS4 insulator element (to reduce reporter gene expression in absence of transactivators), a Tet response element/promoter (see below), a loxP-flanked STOP cassette (stop codons in all three reading frames linked to synthetic pA-hGHpA-PGKpA), a synthetic enhanced green fluorescent protein sequence (EGFP), a woodchuck hepatitis virus post-transcriptional regulatory element (WPRE; to enhance the mRNA transcript stability), a BGH polyA, two copies of chicken beta-globin HS4 insulator element, a CMV-IE enhancer/chicken beta-actin/rabbit beta-globin hybrid promoter (CAG; from pCAGGS), a rox-flanked STOP cassette (stop codons in all three reading frames linked to synthetic pA-hGHpA-TKpA), a synthetic modified tetracycline-regulated transactivator gene (tTA2^S>), a WPRE, a BGH polyA, an AttB site, a PGK-5'hygro cassette, an RNA splice donor and a FRT5 site. The TRE2 promoter used here is Tet-responsive P>hCMV*-1<; containing the Tet response element (seven copies of the 19 bp tet operator sequence [tetO]) just upstream of a minimal cytomegalovirus promoter (P>min CMV<), which lacks the enhancer that is part of the complete CMV promoter. Consequently, P>hCMV*-1< is silent in the absence of tTA or rtTA binding to tetO. PhiC31-mediated recombination removed the AttB/AttP-flanked sequence and replaced it with the recombined AttB/AttP site (AttL). (J:260362)
