Genetic information | To generate Miwi2 D761A allele the wild-type exon 17 was replaced with a mutant exon where the aspartic acid 761 codon is mutated to encode an alanine. A targeting construct was recombineered that contains homology arms, an frt flanked neomycin (neo) cassette 3' of exon 17 that contains the Miwi2 D761A mutation; flp-mediated recombination caused an excision of the Neor-frt flanked cassette that results in the Miwi2 DAH allele. |
Phenotypic information | Homozygous male and female mice for Miwi2 DAH allele are viable, healthy and fertile. Miwi2 DAH mice do not present any apparent abnormalities. |
Breeding history | Mice carrying the targeted allele were crossed with flp-expressing transgenic mice (FlpeR) to remove the Frt-flanked Neor cassette. The resulting offspring was backcrossed to C57BL/6N to remove the FLP transgene. Mice carrying the mutation were then backcrossed 8 generations to C57BL/6N. |
