| Genetic information | Promoterless reporter gene (NotI-NheI fragment of the vector pSA-betaGeolox2PGKDTA) 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 heterozygous mice with transgenic Nes cre mice on C57BL/6 genetic background, the Bclaf1-/- Nes cre+ mice are chimeras. Where the Nes promoter-driven cre recombinase is well expressed (brain, spinal cord and optic nerve), 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 Nes promoter-driven cre recombinase expression (liver, aorta, fat tissue, thymus, spleen, lymph nodes, bone marrow) the genotype of the mice is Bclaf1-/- Nes cre+. |
| Phenotypic information | Most of the Bclaf1-/- Nes cre+ mice survive to normal life span, but show slightly reduced body weight. The males are infertile, the females have problems with breeding: they get no newborn mice (resorption of embryos?) or get only a small number of newborn mice (1-4) or sometimes giant newborn mice (1-2). Bclaf1-/- Nes 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 Nes 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 nestin promoter (Nes cre) on C57BL/6 background. Homozygous males are infertile - Homozygous females have problems with breeding - Please see phenotype description! |
