Strain development Developed by Takashi Sado, National Institute of Genetics in 2006. J1 ES cells were used to generate the mutant mice. Puromycin resistance was excised by crossing with cre transgenic mice.  
Strain description Tsix gene splicing knockout mice (Tsix<SA>). The splicing acceptor site of Tsix exon 4 was replaced with a fragment containing an IRES-EGFP and a floxed puromycin resistance gene. This mutant line carries modified allele of Tsix locus to avoid the production major splicing variant. Heterozygote mutant females with paternal mutant allele were embryonic lethality by non-random and abnormal X-inactivation. Tsix knockout (Xist<1loxGFP>)(RBRC01949), Tsix splising (Tsix<SA>)(RBRC01949), Xist/Tsix double knockout (X<dc>)(RBRC01950), Tsix<pA> (RBRC02653), Xist<IVS> (RBRC02654), Xist<delta> (RBRC02655).
