Mouse Strain information
APB ID 1929
Added 23/08/2007
Last Edited 11/05/2014
Strain name: C.129P2-Stat6tm1Aki/AnuApb
Nickname: Balb/C Stat6-/- N10
Strain designation name: C.129P2-Stat6tm1Aki/AnuApb
Strain Types Mutant strain
Genetic Details Targeted knockout
Mode of Inheritance Recessive
1.  Affected Gene Name: signal transducer and activator of transcription 6  
Chromosome 10
Affected Gene Symbol Stat6
Protein expression of altered gene: Nil
Genetic alteration of gene: The 3 exons encoding the SH2 domain were replaced with a neomycin resistance gene via homologous recombination. Northern blot analysis of splenocytes from homozygous mutant animals using a probe to exons downstream of the deleted region did not detect gene expression.
Location on chromosome (bp): 127080042-127098013 bp, + strand (From Ensembl annotation of NCBI Build 37)

Allele Name signal transducer and activator of transcription 6; targeted mutation 1, Shizuo Akira
Allele Symbol Stat6tm1Aki
MGI Allele Accession ID MGI:2386746
Allele synonyms: Stat6-, STAT6KO
Mutant Construction Technique None
Phenotype Homozygous State Skin inflammation: * mice exhibit mild dermal infiltration of inflammatory cells. * few CD4+ cells infiltrate the perioral dermis and epidermis. Acanthosis: sight. Decreased B cell proliferation: * B cell proliferation in response to anti-IgM plus IL-4 is impaired. * however, B cell proliferation in response to LPS is normal. Decreased T cell proliferation: * thymocyte proliferation in response to TPA is impaired. * however, thymocyte proliferate in response to other stimuli. Decreased IgE level: IgE levels are lower than in wild-type mice following infection with N. brasiliensis. Decreased IgG1 level: IgG1 levels are 16-fold lower than in wild-type mice and following infection with N. brasiliensis they are 10-fold lower than in infected wild-type mice. Increased IgA level: IgA levels are slightly increased following infection with N. brasiliensis. Increased IgG level: IgG2 and IgG3 levels are slightly increased following infection with N. brasiliensis. Abnormal T-helper 2 physiology: mice fail to produce increased levels of Th2 cytokines in response to infection with N. brasiliensis.
