description
Allele Type:    Targeted (Conditional ready, Null/knockout)
Mutations:    Insertion, Single point mutation
 
Mutation detailsA loxP site flanked hygromycin resistance gene and STOP cassette was inserted 100 bp upstream of a Kras mutagenized exon 2 in which valine codon 14 (GTA) was changed to isoleucine (ATA) (p.V14I). Cre-mediated recombination is required for expression of the mutant allele. (J:223433)
