Strain development Developed 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 description Mitogen-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 maintenance Homozygote x Homozygote [or Crossing to C57BL/6JJcl]. Homozygous mutant mice are viable and fertile.
