Mouse Strain information
APB ID 1947
Added 01/09/2007
Last Edited 11/05/2014
Strain name: B6;129P2-Tlr4tm1Aki/AnuApb
Nickname: C57BL/6-TLR-4tm1 ; Teague
Strain designation name: B6;129P2-Tlr4tm1Aki
Strain Types Mutant strain
Genetic Details Targeted knockout
Mode of Inheritance Recessive
1.  Affected Gene Name: toll-like receptor 4  
Chromosome 4
Affected Gene Symbol Tlr4
Protein expression of altered gene: Nil
Genetic alteration of gene: Genomic sequences encoding the transmembrane and cytoplasmic domains (amino acids 86-835) were replaced with a neomycin cassette. Northern blot analysis revealed that no mRNA is produced from this allele in splenocytes derived from homozygous mice.
Location on chromosome (bp): 66488618-66591318 bp, + strand (From VEGA annotation of NCBI Build 37)

Allele Name toll-like receptor 4; targeted mutation 1, Shizuo Akira
Allele Symbol Tlr4tm1Aki
MGI Allele Accession ID MGI:1860885
Allele synonyms: TLR4 KO, TLR4-, TLR4-KO
