Former Names STOCK Gt(ROSA)26Sortm1(Smo/YFP)Amc/J (Changed: 23-MAY-06 ) Type Mutant Stock; Targeted Mutation; Additional information on Genetically Engineered and Mutant Mice. Visit our online Nomenclature tutorial. Mating System Homozygote x Homozygote (Female x Male) 01-MAR-06 Species laboratory mouse Generation N?+1F9 (31-DEC-07) Donating Investigator Andrew McMahon, Harvard University Description
These mice contain an Enhanced Yellow Fluorescent Protein/Smoothened homolog (Drosophila) fusion gene inserted into the Gt(ROSA)26Sor locus. The mutant allele consists of a fusion product involving Enhanced Yellow Fluorescent Protein (EYFP) and the constitutively active W539L point mutation of the mouse smoothened homolog (Drosophila) gene (SmoM2). Expression of the Smo/EYFP fusion gene is blocked by a loxP-flanked STOP fragment placed between the Gt(ROSA)26Sor promoter and the Smo/EYFP sequence. When used in conjunction with a Cre recombinase-expressing strain, successful Cre-mediated excision results in the constitutive expression of mouse smoothened homolog (Drosophila) and unrestrained Hedgehog signaling in Cre-expressing tissues. Expression of the SmoM2 fusion protein can be monitored using EYFP-specific fluorescence protocols. Mice that are homozygous for the mutant allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities.For example, when crossed to a strain expressing tamoxifen inducible Cre recombinase in developing embryos (see Stock No. 004453), in neural progenitor cells (see Stock No. 007684), in cells that received positive hedgehog signalling (see Stock No. 007913), or in cells that express Shh (see Stock No. 005623), this mutant mouse strain may be useful in studies of tumorigenic potential in the hedgehog pathway.
When bred to a strain expressing Cre recombinase in the central nervous system(see Stock No. 004600 for example), this mutant mouse strain may be useful in studies of progenitor cell involvement in the development of medulloblastomas.
When bred to a strain expressing Cre recombinase in midbrain/dorsal spinal cord (see Stock No. 007807 for example), this mutant mouse strain may be useful in studies of craniofacial development.
When bred to a strain expressing Cre recombinase in the nervous system (see Stock No. 003771 for example), this mutant mouse strain may be useful in studies of thalamic development.
Development
A targeting vector containing a loxP flanked PGK-neo-stop cassette upstream of the Yellow Fluorescent Protein/Smoothened homolog (Drosophila) fusion gene (Smo/YFP) was inserted into the Gt(ROSA)26Sor locus. The construct was introduced into 129X1/SvJ-derived AV3 embryonic stem (ES) cells. Correctly targeted ES cells were injected into recipient blastocysts. The resulting chimeric animals were bred to C57BL/6 and outbred Swiss Webster mice. (Additional information from Donating Investigator is forthcoming)

| Yellow Fluorescent Protein (YFP) is a derivative of Green Fluorescent Protein (GFP), a versatile reporter molecule which has found use in many biological applications. The original molecule has been modified in order to enhance fluorescence intensity and shift the wavelength emitted when excited. When YFP is utilized in a transgenic construct, tissue expressing sufficient amounts of YFP will fluoresce yellowish-green when exposed to a 513 nm light source. | |||

| 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 approximately 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 two business days following order placement. |
