Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:221045
• Parent Cell Line: R1 (ES Cell)
• Strain of Origin: (129X1/SvJ x 129S1/Sv)F1-Kitl⁺

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutation: Single point mutation
• Mutation details: A premature stop codon (CAG to TAG) at amino acid residue E1099 (E1099X) was introduced into the linker between domains 2 and 3. The loxP flanked neo cassette downstream of the mutation was removed via cre-mediated recombination. Western blot analysis indicates that global protein expression is reduced to 54.1% in heterozygotes and is undetectable in homozygotes, indicating a null allele. (J:221045)
