Targeted Allele Detail
Symbol: Krastm2(Kras)Rdl
Name: Kirsten rat sarcoma viral oncogene homolog; targeted mutation 2, Roberto Di Lauro
MGI ID: MGI:4830590
Synonyms: KrasKI
Gene: Kras  Location: Chr6:145216699-145250239 bp, - strand  Genetic Position: Chr6, 77.37 cM, cytoband G2
Germline Transmission:  Earliest citation of germline transmission: J:98940
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Inserted expressed sequence, Null/knockout)
Mutation:    Insertion
Mutation detailsA cassette containing Kras cDNA and a neo was fused in-frame with exon 2 such that synthesis of the endogenous Kras product would be abolished. The rearranged locus was designed to express only the main K-Ras 4B isoform and not the K-Ras 4A protein. (J:98940)
