Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:171195
• Parent Cell Line: CJ7 (ES Cell)
• Strain of Origin: 129S1/Sv-Oca2⁺ Tyr⁺ Kitl⁺

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutation: Insertion
• Mutation details: A cassette containing a polyadenylation sequence in the same orientation as Nespas and a self-excising neo cassette was inserted into exon 1. Cre-mediated recombination removed the neo cassette. The absence of Nespas transcript expression was confirmed by RT-qPCR on newborn brain extracts with paternal inheritance of the allele. De-repression of Gnas was confirmed by RT-qPCR. (J:171195)
