Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:72931
• Parent Cell Line: SM1 (ES Cell)
• Strain of Origin: 129S6/SvEvTac

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: Part of exon 9 was replaced with a neomycin selection cassette containing an in frame stop codon that is predicted to cause premature termination of the protein. Nothern blot analysis on RNA derived from brain and other tissues of heterozygous and homozygous mice demonstrated that a truncated transcript is produced from this allele. However, western blot analysis and activity assays confirmed that no functional protein is expressed from this allele in homozygous mice. (J:72931)
