Mouse Strain information
APB ID 347
Added 25/09/2006
Last Edited 11/05/2014
Strain name: B6;129S1-Cited2tm1.1Dunw/Apb
Nickname: C2f
Strain designation name: B6;129S1-Cited2tm1.1Dunw/Apb
Strain Types Mutant strain
Genetic Details Targeted reporter
Targeted floxed
ES Cell-Line Used W9.5
Mode of Inheritance Semi-dominant
1.  Affected Gene Name: Cbp/p300-interacting transactivator, with Glu/Asp-rich carboxy-terminal  
Chromosome 10
Affected Gene Symbol Cited2
Protein expression of altered gene: Nil
Genetic alteration of gene: LoxP site inserted just upstream of the ATG, loxP-neo-loxP-lacZ cassette inserted downstream of exon 2. After recombinant neomycin resistant clones were selected, the neomycin resistance gene was deleted by partial Cre recombination in vitro. Cited2 expression replaced by lacZ reporter expression
Location on chromosome (bp): 17443032-17444750 bp, + strand (From Ensembl annotation of NCBI Build 37)
