| Genetic information | Promoterless reporter gene (NotI-NheI fragment of the pSA-betaGeo-lox2PGKDTA vector) containing a loxP-flanked cassette of splice acceptor, beta-galactosidase/lacZ gene and neo gene; inserted into intron between Bclaf1 exon 3 (translation start at ATG) and exon 4 by targeted mutagenesis. After breeding of heterozygous mice with transgenic Vav-cre mice on C57BL/6 genetic background the Bclaf1-/- Vav-cre+ mice are chimeras. Where the Vav promotor-driven cre recombinase is well expressed (bone marrow, spleen, blood cells, heart and lung), the Bclaf1 genotype switches from -/- via -/del to del/del (wild-type with an additional loxP site in the intron between exon 3 and 4 due to removal of loxP-flanked marker cassette). In organs without Vav promotor-driven cre recombinase expression (ear, eye, tong, optic nerve) the genotype of the mice is Bclaf1-/- Vav-cre+. |
| Phenotypic information | All Bclaf1-/- Vav-cre+ mice survive to normal life span with normal body weight. The males and females are fertile. Bclaf1-/- Vav cre-(minus) mice survive only 2-4 weeks and have 70-80% body size at birth and 35-75% body weight at 14 d age compared to littermates. If older than 2 weeks they move slowly, lay sometimes for a short time on the side, some behave sometimes like epileptically for a short time; they do not learn rearing and climbing; lower body temperature starts 4 days postnatally, lower blood glucose starts 7 days postnatally. The Bclaf1 Vav cre-(minus) mice are deposited as Bclaf1 RK BL6 on C57BL/6 background, at EMMA since 2006 (strain EM:01978). |
| Breeding history | Bclaf1 knock-out line backcrossed to C57BL/6 more than 10 generations (inbred); breeding with transgenic line expressing cre recombinase under Vav1 oncogene (Vav-cre) on C57BL/6 background. |
