Germline Transmission:  Earliest citation of germline transmission: J:67969
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsReplacement of exon 9, encoding a proteolytic cleavage site, and flanking intronic sequence with a neomycin cassette. A reduced level of mRNA was detectable by RT-PCR from this allele; sequence analysis revealed splicing from exon 8 to exon 10 without frameshift. However, Western blot analysis revealed that expression of the protein was abolished, and this allele is suggested to be a null. (J:67969)
