Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:58298
• Parent Cell Line: J1 (ES Cell)
• Strain of Origin: 129S4/SvJae

Mutation description

• Allele Type: Targeted (Null/knockout, Reporter)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A 0.3kb region encoding the PC and ENV motifs was replaced with a cassette containing an IRES-lacZ gene and a neo gene. Northern blot analysis of total RNA showed an absence of transcript in homozygous mutant mice. X-gal staining of heterozygous embryos revealed expression of beta-galactosidase. (J:58298)
