| Genetic information | For the knock-in model, the sequences of mouse Tfrc (aa. 196-381) were replaced with the sequences of human TFRC (aa. 194-379). As templates for the generation of the targeting vector, BAC RP24-363L9 and RP23-206N24 from the C57BL/6 library and RP11-480A16 were used. C57BL/6 ES cells (Cyagen) were used to target the Tfrc gene in C57BL/6 mice. This resulted in mice expressing a TFRC protein with a humanized apical domain (API). |
| Phenotypic information | Homozygous:No obvious phenotype is found. Mice are normal, viable, fertile, and produce normal sized litters.Heterozygous:Heterozygous pups are smaller and weaker compared to their wild-type and homozygous littermates. Heterozygous mice catch up the weight differences and appear viable and fertile. This phenotype is not studied in detail, but as TFRC acts as a dimer we believe it may be due to less functional dimers containing wild-type mouse TFRC and the humanized API_TFCR in the heterozygous animals. |
| Breeding history | This strain was generated by Cyagen and F1 heterozygous animals were crossed to generate homozygous offspring. The mice were kept for 8 generations as homozygous breeders. |
