Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:194592
• Parent Cell Line: AB1 (ES Cell)
• Strain of Origin: 129S7/SvEvBrd-Hprt1⁺

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutation: Insertion
• Mutation details: A neomycin resistance cassette was inserted into exon 3. The truncated protein is predicted to be inactive and also lack the cysteine at position 352 which is ADP-ribosylated by pertussis toxin. No protein was detected in homogenates from homozygous mice by ADP-ribosylation with pertussis toxin. The absence of protein was also confirmed by immunoblotting. (J:24434, J:194592)
