Strain Details
Type JAX® GEMM® Strain - Congenic Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Strain Type JAX® GEMM® Strain - Transgenic Mating System +/+ sibling x Hemizygote (Female x Male) Species laboratory mouse Donating Investigator IMR Colony, The Jackson Laboratory Generation N10F1 (19-DEC-07) Strain Description
Mice that are homozygous for this "MerCreMer" double fusion protein 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. As the cre is flanked on each end with a mutated murine estrogen receptor ligand binding domain (amino acids 281-599, G525R); Cre expression is tamoxifen inducible yet estrogen insensitive. 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.In an attempt to offer alleles on well-characterized or multiple genetic backgrounds, alleles are frequently moved to a genetic background different from that on which an allele was first characterized. It should be noted that the phenotype could vary from that originally described. We will modify the strain description if necessary as published results become available.
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 were subsequently backcrossed to C57BL/6J mice for 5 generations.

| Allele Name | transgene insertion 1, Jeffery D Molkentin | ||
| Common Name(s) | MCM; MerCreMer; alpha-MHC-MerCreMer; mer; | ||
| 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 | Esr1, estrogen receptor 1 (alpha), mouse, laboratory | ||
| 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. | |||
| 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. [MGI Ref ID J:82027] | ||

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 and Purchasing Information
