Generation DefinitionsDonating Investigator Rudolf Jaenisch, Whitehead Institute (MIT) Description
Homozygotes are viable, fertile, normal in size and do not display any behavioral abnormalities. These targeted mutant mice have widespread expression of an optimized form of reverse tetracycline-controlled transactivator (rtTA-M2) protein. This R26-M2rtTA strain may be useful for doxycycline-inducible studies which utilize rtTA/tet-O (tet-on/TRE) models.Development
A targeting vector was designed to insert an optimized form of reverse tetracycline controlled transactivator (rtTA-M2) followed by a β-globin intron and polyA signal downstream of the Gt(ROSA)26Sor promoter. This construct was electroporated into (C57BL/6 x 129S4Sv/Jae)F1-derived V6.5 embryonic stem (ES) cells. In addition, these ES cells were retargeted to insert an frt-flanked PGK-Neo was into the 3' UTR of the Col1a1 locus. Correctly targeted ES cells were selected and the frt-flanked PGK-Neo in the 3' UTR of the Col1a1 locus was replaced by injecting both a "flip-in plasmid" containing a splice acceptor-double polyA sequence and the tetracycline responsive element (TRE or tetO) upstream of the mouse Oct4 (Pou5f1) cDNA sequence, as well as a Flpe-expressing plasmid to facilitate tetO-Oct4 recombination into the 3' UTR of the Col1a1 locus. The resulting ES cells (now targeted with rtTA-M2 in the Gt(ROSA)26Sor locus and tetO-Oct4 in the Col1a1 locus) were injected into B6D2F1 tetraploid blastocysts. Chimeric mice were bred together for many generations prior to arrival at The Jackson Laboratory (as Stock No. Stock No. 006911). Upon arrival, a subset of mice were backcrossed to C57BL/6J; selecting mice harboring the mutant Gt(ROSA)26Sor allele (not harboring the Col1a1 mutant locus) for at least 5 generations to generate this congenic strain (Stock No. 006965).

| Site of Expression | Expresses an optimized rtTA protein (rtTA-M2). Inducible target gene expression is detected in liver, bone marrow, stomach, intestine, and skin, with lower levels in the heart, lungs, kidney, spleen, and thymus; no expression is detected in the brain and testes. | ||
| Expressed Gene | rtTA, reverse tetracycline-controlled transactivator, E. coli | ||
| The tetracycline repressor gene (Tetr), arose from chemically mutated Escherichia coli genome which was screened for tetracycline dependence (Gossen and Bujard, 1992). One mutant with a four amino acid residue change (rTetR) exhibited dependence on tetracycline for induction of the targeted gene and was used in the rtTA construct (Gossen et al, 1995). rTetr was fused at the C-terminus with the viral co-activator, virion protein 16 of the herpes simplex virus (VP-16). | |||
| General Note | This mutation is always used in combination with the Col1a1tm2(tetO-Pou5f1)Jae allele in the same mouse line. Mutant ES cell line = KH2. | ||
| Molecular Note | An optimized form of reverse tetracycline controlled transactivator (rtTA-M2) was inserted downstream of the Gt(ROSA)26Sor promoter. This mutant form of rtTA termed M2 has five amino acid substitutions in the tetR moiety of tTA: S12G, E19G, A56P, D148E and H179R. This mutated form of transactivatory protein has increased doxycycline sensitivity. Mice have widespread expression of the rtTA-M2 protein. [MGI Ref ID J:98920] | ||

The Jackson Laboratory's Genotype Promise
The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.Ordering Information
