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 details: Glycine 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)
