Gene Information

Gene Details

Atm1Brd
Name: nonagouti; targeted mutation 1, Allan Bradley
Type: Allele
Species: Mus musculus (mouse)
Chromosome: 2
Alteration at locus: Targeted Mutation
Genetic Alterations
These cells were a sub-clone of procedures used to generate the JM8A cell lines, and subsequently made to be feeder independent. The nonagouti mutation in C57BL/6 strains is due to the presence of an 11.8 kilobase pair (kbp) retrotransposon in the first intron of the Agouti gene which abolishes transcription of Agouti mRNA15. JM8.F6 ES Cells were targeted to delete the retrotransposon from the locus and restore Agouti gene function. The retrotransposon was replaced with a selectable marker, which was subsequently removed by Flp recombinase. The resulting Agouti allele contains a net deletion of 607 bp of intron sequence relative to the 129 strain Agouti allele and the retention of a single Flp recombinase target (FRT) site. Subsequently, a small fragment of the targeting vector also integrated into a section of Chromosome 8, and therefore targeting Chromosome 8 with these cells is not recommended, and we recommend instead either the JM8.N4 or JM8.F6 ES Cells.

Colony and Husbandry Information

Special Considerations

These cells are expected to be male (XY), are feeder-dependent, and homozygous (a/a) for the a, non-agouti, coat color allele.

Health Status Report

Requested cell lines are tested by PCR analysis for mycoplasma spp. and Murine Parvoviruses (MPV) upon completion of expansion and prior to shipment. The JM8 Parental Cell Line, from which these cells were derived, was tested for multiple mouse pathogens and all results were negative. The specific JM8A1.N3 Parental Cell Sub-line was also tested for multiple mouse pathogens; please see the Health Status Report.

Mice derived from requested cell lines via Microinjection services will be pathogen tested prior to delivery of mice and health reports will be provided. If you require additional health status information prior to requesting microinjection please email mmrrc@ucdavis.edu.
