Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:73926
• Parent Cell Line: DBA-252 (ES Cell)
• Strain of Origin: DBA/1LacJ

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A PGK-neomycin resistance cassette replaced about 1.8 kb of sequence including exons 3-8, which correspond to amino acids 56-303. Isotope binding studies did not detect glucagon binding on liver membranes isolated from homozygous mutant mice. (J:73926)
