BRC No.RBRC01388
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6;129P2-Keap1<tm1Mym>/MymRbrc
Former Common nameKeap1 knockout mice
H-2 Haplotype
ES Cell lineE14 [129P2/OlaHsd]
Background strain
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Masayuki Yamamoto, Center for Tsukuba Advanced Research Alliance, University of Tsukuba in 2003. Sequence encoding 8 through 204 of Keap1 was replaced with neomycin and nls-lacZ cassette.
Strain descriptionKeap1 gene is a cytoplasmic protein, acts as a negative regulator of Nrf2 and as a sensor of xenobiotic and oxidative stresses. Double knockout mice of Nrf2 and Keap1 demonstrated that Nrf2 is a primary target of Keap1. Nrf2-Keap1 system is one of the major cellular protection mechanisms against xenobiotic and oxidative stresses. Keap1 homozygous mutant mice exhibit scaly skin, hyperkeratosis in the esophague and forestomatch, and died postnatally.
Colony maintenanceHeterozygote x Wild-type [C57BL/6JJcl]. Homozygous mutant mice are postnatal letha.
