Strain nameB6.129P2-Map2k4<tm1Pngr>/Rbrc
Former Common nameSEK1 Knockout mice
H-2 Haplotype
ES Cell line
Background strainC57BL/6JJcl
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Dr. Hiroshi Nishina at Ontario Cancer Institute, University of Toronto in 1997. A neomycin selection cassette was inserted into the exon 2 of the SEK1 gene. The SEK1 deficient mice were backcrossed to C57BL/6 over 13 times.
Strain descriptionB6.129P-Map2k4<tm1Pngr>. The stress signaling kinase SEK1/MKK4 is a direct activator of stress-activated protein kinase, or Jun N-terminal kinases (SAPKs/JNKs) in response to environmental stress or mitogenic factors. Homozygous mutant mice exhibit severe anemia and die between embryonic day 10.5 and 12.5. This mutant strain is useful for the study of SEK1 gene function.
Colony maintenanceBackross to C57BL/6 (Heterozygote x C57BL/6J)Homozygous mutant mice die between embryonic day 10.5 and 12.5.
