Genetic Alterations
ENU-induced A to T transversion at base pair 126,763,512 (v38) on chromosome 7, or base pair 4,114 in the GenBank genomic region NC_000073 for the Mapk3 gene. The mutation corresponds to residue 681 in the mRNA sequence NM_011952 within exon 4 of 9 total exons. The mutation results in substitution of lysine (K) 221 to a premature stop codon in the ERK1 (alternatively, p44) protein.
Phenotype

Homozygous: Mice showed decreased secretion of the proinflammatory cytokine interleukin (IL)-1β in response to priming with lipopolysaccharide (LPS) followed by nigericin treatment.

Heterozygous: No abnormal phenotype detected.

Mammalian Phenotype Terms
Allelic Composition: (Genetic Background: )

  • immune system
    • decreased interleukin-1 beta secretion [MP:0008658]
Strain Development
Original mutant was a C57BL/6J G3 ENU-induced mutant; all subsequent crosses to maintain strain were on C57BL/6J background only.
Suggested Control Mice
Wild-type littermates or C57BL/6J mice
  • Immunology and Inflammation
