Mouse Strain information
APB ID 1634
Added 17/07/2007
Last Edited 11/05/2014
Strain name: 129/Sv-Itsn1tm1.1Mapr/Apb
Nickname: Itsn1Total KO +/- 129Sv
Strain designation name: 129/Sv-Itsn1tm1.1Mapr/Apb
Genetics
Strain Types Mutant strain
Genetic Details Targeted knockout
ES Cell-Line Used TC1 (129SvJ)
Mode of Inheritance Recessive
1.  Affected Gene Name: intersectin 1 (SH3 domain protein 1A)  
Chromosome 16
Affected Gene Symbol Itsn1
Protein expression of altered gene: Nil
Genetic alteration of gene: A neo cassette with a 5' loxP site was inserted upstream of exon 3 and an additional loxP site was inserted downstream of exon 3. Transient cre expression in ES cells was used to removed the neo cassette and exon 3 causing a frame shift and premature termination of translation. The absence of the short and long forms of the protein was confirmed by western blot analysis on brain and heart extracts.
Location on chromosome (bp): 91618140-91809456 bp, + strand (From VEGA annotation of NCBI Build 37)
