| Genetic information | Exon 2, encoding amino acids 44-130, was replaced by a neomycin cassette. No protein was detectable in Western blots of immunoprecipitates of MEF lysates derived from homozygous mutant embryos. |
| Phenotypic information | Homozygous:Some mice die between 9 and 18 months of age; these mice have no evidence of tumors but have severe extra-medullary hematopoiesis. Abnormal lymphocyte morphology, spleen and lymph nodes hyperplasia, 8.2% incidence of tumors. MEFs exhibit a higher proliferation rate and they are susceptible to Ras-induced transformation.Heterozygous:Heterozygous mice are viable |
| Breeding history | Chimeras were bred with C57BL/6J females. Heterozygous mice were bred among themselves to generate homozygous mice or to C57BL/6J animals to propagate the targeted allele. Mice were bred for more than 10 generations with C57BL/6J mice before freezing. |
