Type JAX® GEMM® Strain - Gene Trap Additional information on JAX® GEMM® Strains. Type JAX® GEMM® Strain - Mutant Stock Type JAX® GEMM® Strain - Targeted Mutation Mating System Heterozygote x +/+ sibling (Female x Male) Species laboratory mouse Donating Investigator Philippe Soriano, Fred Hutchinson Cancer Research Center Generation ?+N0 (10-JUL-08) Strain Description
Homozygotes for the Smad1tm1Sor (also called Smad1C) allele have an embryonic lethal phenotype and do not survive past ED9.5. These mice carry a mutation (the C-terminal SSVS motif was changed to AAVA) in exon 7, which effects transcriptional activity. Homozygous embryos display posterior truncation, abnormal turning, allantois malformations (failure of the allantois to connect to the chorionic plate), anterior truncation of the head with only one brachial arch, and enlarged pericardium. At ED7.5 homozygous embryos do not have any detectable primordial germ cells. Western blot analysis of ED9.5 homozygotes showed that protein levels were not affected. Heterozygotes for this mutant allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. This mutant mouse strain may be useful in studies of homeostasis and BMP and MAPK signaling pathways during development and in the adult.Strain Development
A targeted vector containing a floxed PGKneo selection cassette and a diphtheria toxin selection cassette was used to introduce a mutation (the C-terminal SSVS motif was changed to AAVA) in exon 7. Correctly targeted ES cells were injected into recipient blastocysts. The mice were crossed to a strain expressing Cre under the control of the Meox2 promoter to remove the floxed PGKneo cassette. The mice were then crossed to mice carrying the Smad1tm2Sor mutant allele prior to arriving at The Jackson Laboratory. Upon arrival, mice were bred to C57BL/6J to separate the mutant alleles. These mice carry only the Smad1tm1Sor (also called Smad1C) mutant allele.

| Molecular Note | A floxed neo was introduced upstream of exon 7 and within exon 7, the C-terminal SSVS motif was changed to AAVA. Cre-mediated recombination excised the neo, leaving the mutated exon 7. Western blot of embryonic protein extracts indicated that mutant embryos showed similar levels of protein as that in wild type.

Supply Details
| 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. |

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
