Excision of the floxed region results in the expression of a defective, amino-terminally truncated "RINGless" polypeptide that initiates at methionine residue M90 or M99 (Li, 2016). Targeted inactivation in mammary epithelial cells in females results in the development of mammary tumors that resemble the basal-like triple-negative breast tumors of human BRCA1 mutation carriers (Shakya, 2008). |

Widespread, homozygous knock-out of the gene is embryonic lethal (Reczek, 2016), while progenitor B cell-specific inactivation of the gene (created through crosses with Cd79atm1(cre)Reth (Stock No. 020505) mice) impairs early B cell development (Liu, 2019). |

NOD:Alox15loxP mice possess loxP sites flanking exons 2-5 of the arachidonate 15-lipoxygenase (Alox15) gene on the diabetes susceptible NOD/ShiLtJ background. These floxed mice are useful for tissue specific deletion of Alox15 when studying obesity and diabetes. 12/15-LOloxP/loxP is available on the C57BL/6 background as Stock No. 031835. |
037514 | C57BL/6J-Appbp2em1Kajim/J | Appbp2 flox | Appbp2 flox mice, in which exon 2 of the mouse Appbp2 (amyloid beta precursor protein (cytoplasmic tail) binding protein 2) gene is flanked by loxP sites, may be useful for studying the role of the gene in the regulation of thermogenesis, obesity, and diabetes. Cre recombinase-mediated excision of the floxed region results in a knock-out allele. |
037267 | B6J.Cg-Mettl5em1.1Snac/J | Mettl5 floxed | Exon 2 of the mouse Mettl5 (methyltransferase like 5) gene is flanked by loxP sites. Cre recombinase-mediated excision of the exon results in a knock-out allele useful in studies of methylation, mRNA translation, and metabolic dysregulation. Of note, the donating investigator has also made a derived Mettl5 knock-out mouse line available (Stock No. 037268). |
037268 | STOCK Mettl5em1.2Snac/J | Mettl5<-> | Exon 2 of the mouse Mettl5 (methyltransferase like 5) gene has been excised to create this knock-out allele that is useful in studies of methylation, mRNA translation, and metabolic dysregulation. Of note, the donating investigator has also made a Mettl5 floxed mouse line available (Stock No. 037267). |
037393 | B6.Cg-Gt(ROSA)26Sorem1(CAG-Cd55*)Hgr/J | DAF-TM | DAF-TM mice have a CRISPR/Cas9 generated insertion of a floxed STOP cassette and a mutated Cd55 gene inserted into the endogenous Gt(ROSA)26Sor locus. Specifically, the DAF-TM sequence contains the complement regulatory domain of the CD55 molecule, decay accelerating factor for complement (Cd55) gene, and the signal sequence for glycophosphatidylinositol-(GPI)-anchor addition of Cd55 replaced with that of the transmembrane helix domain of human tissue factor. When crossed with a Cre recombinase expressing strain, removal of the floxed STOP cassette will result in DAF-TM expression in Cre expressing tissues. These mice may be useful for studying complement activation and signaling cascades. |
037569 | C57BL/6J-Henmt1em1Pdz/J | Henmt1 |
Henmt1em1 mutant mice carry a CRISPR/cas9-generated mutation of the mouse Henmt1 (HEN1 methyltransferase homolog 1 (Arabidopsis)) gene. Transcription of the targeted gene is unperturbed, but the mutation in exon 4 results in a loss of catalytic activity and reduced expression of the protein. These mice are useful for studies of spermatogenesis, and piRNA biogenesis. |
