Mouse Strain information
APB ID 201
Added 18/04/2006
Last Edited 24/04/2015
Strain name: B6;129S1-Tgfbr3tm1Stv/Apb
Nickname: TGFbRIII KO
Strain designation name: B6;129S1-Tgfbr3tm1Stv/Apb
Strain Types Mutant strain
Genetic Details Targeted knockout
Mode of Inheritance Recessive
1.  Affected Gene Name: transforming growth factor, beta receptor III  
Chromosome 5
Affected Gene Symbol Tgfbr3
Protein expression of altered gene: Nil
Genetic alteration of gene: A PGK-Neo expression cassette was inserted in the "sense" orientation into exon 2. Homologous recombination was verified by Southern blot analysis. Two weak bands representing aberrent transcripts were seen in northern blots of mRNA from embryos homozygous from the targeted gene. RT-PCR analysis confirmed that none of these transcripts represented wild-type mRNA and affinity labelling of embryo fibroblasts with TGFbetaI indicated that there was no binding to TGFbetaRIII.
Location on chromosome (bp): 107535589-107718648 bp, - strand (From NCBI annotation of NCBI Build 37)
