Mouse Strain information
APB ID 4991
Added 28/01/2010
Last Edited 19/05/2014
Strain name: C57BL/6-Ticam1Lps2/BtlrAnuApb
Nickname: Lps2
Strain designation name: C57BL/6-Ticam1Lps2/BtlrAnuApb
Genetic Details Chemically induced : ENU
Mode of Inheritance Recessive
1.  Affected Gene Name: toll-like receptor adaptor molecule 1  
Chromosome 17
Affected Gene Symbol Ticam1
Genetic alteration of gene: ENU mutagenesis induced the deletion of a single guanine within codon 708, resulting in a frameshift mutation. The mutation was predicted to replace 24 C-terminal residues with 11 unrelated residues. The mutation was initially detected by screening macrophages for their competence to respond to LPS.
Location on chromosome (bp): 56408742-56416209 bp, - strand (From VEGA annotation of NCBI Build 37)

Synonyms TICAM-1, Trif
Allele Name toll-like receptor adaptor molecule 1; lipopolysaccharide 2
Allele Symbol Ticam1Lps2
MGI Allele Accession ID MGI:2679794
Allele synonyms: Lps, Lps2-, Ticam1-, TRIF-, TrifLps2, Trifm
Mutant Construction Technique None
Phenotype Homozygous State Abnormal cytokine secretion: * cytokine secretion induced by naked polyI:C is severely impaired by 5- to 10-fold. * however, secretion induced by transfected polyI:C is unaffected Decreased susceptibility to endotoxin shock: though some mice became ill and died after intraperitoneal LPS injection, the survival rate was significantly greater than that of wild-type. Increased susceptibility to viral infection: no production of type I interferons in response to mouse cytomegalovirus (mCMV).
