Generation DefinitionsDonating Investigator Richard Locksley, Univ of California San Francisco-HHMI Description
Mice homozygous for this bicistronic "yet40" allele are viable, fertile, normal in size and do not display any gross physical or behavioral abnormalities. The IRES-EYFP is inserted downstream of the endogenous stop codon, allowing for normal expression of the endogenous gene and simultaneous EYFP reporter expression. ELISA assays confirm that p40 protein is expressed at similar levels in homozygous mutant and wildtype mice. The EYFP reporter marks dendritic cell (DC) and macrophage lineage cells that produce p40 following stimulation with toll-like receptor (TLR) ligands both in vivo and in vitro. These mice may be useful for labeling activated IL12/23 p40 expressing cells in studies of immunology and immunity, TLR signal cascades, cancer immunity, and vaccine development.Development
A targeting vector was designed to insert an internal ribosomal entry site-enhanced yellow fluorescent protein (EYFP; Clontech) sequence followed by a bovine growth hormone poly(A) signal and a loxP-flanked neomycin resistance cassette downstream of the stop codon in exon 8 of the endogenous gene. The construct was transfected into 129Sv-derived PrmCre embryonic stem (ES) cells. Correctly targeted ES cells were injected into C57BL/6 blastocysts. Because the ES cells express Cre recombinase under the direction of the mouse protamine 1 promoter (expresses in testis/male germline), the neomycin resistance cassette was deleted in the male germline. Chimeric males were bred to wild-type C57BL/6 females, and heterozygotes were backcrossed to C57BL/6 for at least 10 generations prior to arrival at The Jackson Laboratory. During the backcrossing, the Prm-cre transgene was eliminated from the strain.

| Expressed Gene | YFP, Yellow Fluorescent Protein, jellyfish | ||
| 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. | |||
