Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout, Reporter)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExons 2 through 4 were replaced with a cassette containing beta-galactosidase and neomycin resistance genes. The deleted region contained two start codons encoding high-molecular weight isoforms and 80kD isoforms in exons 2 and 4, respectively. Transcript was undetected by Northern blot analysis using a carboxy terminal coding sequence probe. An 80kD protein was detected in wild-type but not in homozygous mutant mice via Western blot analysis. (J:77852)
