1 Capecchi, Mario R.Illegitimate cre-dependent chromosome rearrangements in transgenic mouse spermatids.The bacteriophage P1 Cre/loxP system has become a powerful tool for in vivo manipulation of the genomes of transgenic mice. Although in vitro studies have shown that Cre can catalyze recombination between cryptic "pseudo-loxP" sites in mammalian genomes, to date there have been no reports of loxP-si...Chromatin; Female; Mice, Inbred C57BL; Phenotype2000-12-05
2 Capecchi, Mario R.Removing the vertebrate-specific TBP N terminus disrupts placental beta2m-dependent interactions with the maternal immune systemMammalian TBP consists of a 180 amino acid core that is common to all eukaryotes, fused to a vertebrate-specific N-terminal domain. We generated mice having a modified tbp allele, tbp(DeltaN), that produces a version of TBP lacking 111 of the 135 vertebrate-specific amino acids. Most tbp(DeltaN/Delt...Alleles; Animals, Genetically Modified; Binding Sites; Embryonic and Fetal Development; Evolution, Molecular; Female; Fetus; Immune Tolerance; Male; Mice; Mutation; ATA-Box Binding Protein2002-07-12
