Strain Data Sheet


Strain Information

BRC No.RBRC02192
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129-Mapk14<tm1.2Otsu>
Former Common namep38α-flox mouse
H-2 Haplotype
ES Cell lineR1 [(129X1/SvJ x 129S1/Sv)F1-Kitl<+>]
Background strainC57BL/6JJcl
Appearanceblack [a/a B/B C/C]
Strain developmentDeveloped by Kinya Otsu, Osaka University Graduate School of Medicine in 2000. The targeting construct was electoroporated into R1 ES cells derived from (129X1/SvJ x 129S1/Sv)F1-Kitl<+>. The mutant mice were backcrossed to C57BL/6J.
Strain descriptionMitogen-activated protein (MAP) kinase cascades are highly conserved signal transduction pathways involved in a variety of physiological events. The MAP kinase family consists of extracellular signal-regulated protein kinase (ERK), c-Jun NH2-terminal protein kinase (JNK), and p38 MAP kinase. p38 alpha, one of the p38 MAP kinase subfamily, is widely expressed and has an important function in cytokine production and the response to many types of stress. Because p38alpha-deficient mice (BRC00361 C57BL/6-TgH(p38)/118) showed embryonic lethality at midgestation, this strain is useful for the research of p38 MAP kinase pathway in various tissues using Cre-loxP system.
Colony maintenanceHomozygote x Homozygote [or Crossing to C57BL/6JJcl]. Homozygous mutant mice are viable and fertile.
