Dnmt1^tm1Jrc
Targeted Allele Detail

Summary

• Symbol: Dnmt1^tm1Jrc
• Name: DNA methyltransferase 1; targeted mutation 1, J Richard Chaillet
• MGI ID: MGI:2387992
• Synonyms: Dnmt1^delta1o
• Gene: Dnmt1 Location: Chr9:20818501-20871084 bp, - strand Genetic Position: Chr9, 7.66 cM
• Alliance: Dnmt1^tm1Jrc page

Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:68455
• Parent Cell Line: W9.5/W95 (ES Cell)
• Strain of Origin: 129S1/Sv-Oca2⁺ Tyr⁺ Kitl⁺

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: The oocyte-specific exon 1o and the proximal promoter region were deleted and replaced with a floxed HSV-tk-PGK-neo cassette. The resistance cassette was removed by transient expression of cre recombinase in correctly targeted ES cells. Immunohistochemical analysis of ovary sections from homozygous mutant animals confirmed the absence of gene expression in mutant oocytes. (J:68455)
