Type JAX® GEMM® Strain - Mutant Stock Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Transgenic Mating System Homozygote x Homozygote (Female x Male) Species laboratory mouse Donating Investigator Jeffery Molkentin, Children's Hospital Medical Center Generation +N1F5 (05-DEC-07) Strain Description
Mice that are homozygous for the transgene are viable, fertile, normal in size, and do not display any gross physical or behavioral abnormalities. Cre expression in heart tissue is confirmed by western blot. Southern blot confirmed heart cell specificity compared to brain, kidney, lung, liver, and skeletal muscle. Insertion of this transgene and its protein show no changes in echocardiography, heart mass or pathology, or hypertrophy marker genes compared to nontransgenic littermates. Of note, this double fusion protein has substantially greater Cre recombinase activity with less promiscuity compared with a single CreMer fusion protein. Inducible expression of cre in cardiac cells makes this strain suitable for creating bitransgenic mice for use in studies of temporally regulated deletion of loxP-flanked targeted genes.Strain Development
A transgenic construct using the cardiac-specific murine alpha-myosin heavy chain promoter to direct expression of a double fusion protein was injected into FVB/N embryos. This double fusion protein, MerCreMer, has cre recombinase gene flanked on each end with a mutated murine estrogen receptor ligand binding domain (amino acids 281-599, G525R); thus rendering Cre expression tamoxifen inducible yet estrogen insensitive. These embryos were implanted into pseudopregnant FVB/N females. Founder animals were backcrossed to mice with a (B6 x 129/Sv)F1 genetic background for 15 generations and are now interbred.

| Mutation Made By | Jeffery Molkentin, Children's Hospital Medical Center | ||
| Strain of Origin | FVB | ||
| Site of Expression | tamoxifen inducible (yet estrogen insensitive) Cre recombinase protein fused to two mutant estrogen-receptor ligand-binding domains (MerCreMer); expression in developing and adult heart | ||
| Expressed Gene | cre, cre recombinase, bacteriophage P1 | ||
| Cre recombinase is an enzyme derived from the bacteriophage P1 that specifically recognizes loxP sites. Cre has been shown to effectively mediate the excision of DNA located between loxP sites. After the excision event, the DNA ends recombine leaving a single loxP site in place of the intervening sequence. | |||
| Expressed Gene | Esr1, estrogen receptor 1 (alpha), mouse, laboratory | ||
| Promoter | Myh6, myosin, heavy polypeptide 6, cardiac muscle, alpha, murine, murine | ||
| Molecular Note | This transgene expresses a cre recombinase/ mutant estrogen receptor ligand binding domain fusion protein under the control of a mouse cardiac-specific alpha-myosin heavy chain promoter. Expression was detected in the juvenile and adult heart, but the protein is inactive until induced with tamoxifen. [J:82027] | ||

| Standard Supply | Repository-Live. A collection of over 1000 strains maintained as live colonies. Individual colonies are sized to meet current customer demand. Delivery for orders of 10 mice or less ranges on average from one to eight weeks; mice are generally shipped between four to six weeks of age with a maximum shipping age of ~nine weeks. Colony sizes do not generally support stringent age specifications for large volumes of mice; however custom orders and larger quantities of mice are easily arranged. Estimated ship dates for all orders provided within 48 hours of order placement. |
