Mouse Strain information
APB ID 632
Added 25/04/2007
Last Edited 13/06/2011
Strain name: B6;129-Tlr3tm1Flv Eif2ak2tm1Cwe
Nickname: T3DKO
Strain designation name: B6;129-Tlr3tm1Flv Eif2ak2tm1Cwe
Strain Types Mutant strain
Genetic Details Targeted knockout
Mode of Inheritance Dominant
1.  Affected Gene Name: toll-like receptor 3  
Chromosome 8
Affected Gene Symbol Tlr3
Protein expression of altered gene: Unknown
Genetic alteration of gene: The gene was disrupted by replacement of exon 1 with a floxed neo cassette via homologous recombination. Northern blot analysis detected a truncated transcript in mutant animals. The mutant transcript does not encode a functional protein.
Location on chromosome (bp): 46481019-46495893 bp, - strand (From NCBI annotation of NCBI Build 37)

Allele Name targeted mutation 1, Richard A Flavell
Allele Symbol Tlr3tm1Flv
MGI Allele Accession ID MGI:2653138
Allele synonyms: TLR-, Tlr3-
Mutant Construction Technique None
Phenotype Homozygous State Comparable spleen and bone marrow cell populations in tlr3(-/)-, pkr(-/-), and tlr3(-/-)pkr(-/-) mice to wild-type controls. Splenomegaly developing between 8 and 10 weeks of age was observed in tlr3(-/-) and tlr3(-/-)pkr(-/-) mice but not in wild-type or pkr(-/-) mice. These data also suggest that PKR may have a role in preventing progression from splenomegaly to lymphadenopathy in these mice.
