Targeted Allele Detail
Symbol: Dnmt1tm1Jrc
Name: DNA methyltransferase (cytosine-5) 1; targeted mutation 1, J Richard Chaillet
MGI ID: MGI:2387992
Synonyms: Dnmt1delta1o
Gene: Dnmt1  Location: Chr9:20907206-20959888 bp, - strand  Genetic Position: Chr9, 7.66 cM
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+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsThe 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)
