Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:33827
• Parent Cell Line: R1 (ES Cell)
• Strain of Origin: (129X1/SvJ x 129S1/Sv)F1-Kitl⁺

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A neomycin selection cassette replaced a genomic fragment containing exon 2, which encodes the basic-HLH domain essential for dimerization and DNA binding. Western blot analysis on liver cytosol demonstrated that the protein was not detectable in homozygous mice. (J:33827)
