Targeted Allele Detail
Symbol: Trp53tm2Mok
Name: transformation related protein 53; targeted mutation 2, Motoya Katsuki
MGI ID: MGI:2388703
Synonyms: p53-, Trp53tm1.1Mok
Gene: Trp53  Location: Chr11:69580359-69591873 bp, + strand  Genetic Position: Chr11, 42.83 cM, cytoband B2-C
Germline Transmission:  Earliest citation of germline transmission: J:79629
Parent Cell Line:  CCE/EK.CCE (ES Cell)
Strain of Origin:  129S/SvEv-Gpi1c
Allele Type:    Targeted (Null/knockout, Reporter)
Mutations:    Insertion, Intragenic deletion
Mutation detailsThe gene was disrupted using a two-step targeting strategy. First, exons 2-10 were replaced with a neo-TK cassette via homologous recombination. Next, correctly targeted ES cells were subjected to another round of gene targeting to replace the neo-TK cassette with a lacZ cassette. Successful gene replacement was selected for via gancyclovir resistance. Homozygous mutant animals were successfully established. (J:79629)
