Germline Transmission:  Earliest citation of germline transmission: J:73445
Parent Cell Line:  J1 (ES Cell)
Strain of Origin:  129S4/SvJae
Allele Type:    Targeted (Conditional ready, Null/knockout)
Mutations:    Insertion, Single point mutation
Mutation detailsGlycine codon 12 was changed to aspartic acid (p.G12D) to encode an oncogenic form of the KRAS2 protein. A loxP site flanked STOP cassette was included upstream of the inserted Kras2 sequence, such that the mutant transcript would be expressed only after Cre-mediated recombination. (J:73445)
