Targeted Allele Detail
Symbol: Sirt1tm1Ygu
Name: sirtuin 1; targeted mutation 1, Yansong Gu
MGI ID: MGI:3764971
Synonyms: SirT1co, Sirt1flox
Gene: Sirt1  Location: Chr10:63154784-63174814 bp, - strand  Genetic Position: Chr10, 32.57 cM
Germline Transmission:  Earliest citation of germline transmission: J:121948
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Conditional ready, No functional change)
Mutation:    Insertion
Mutation detailsA floxed neomycin cassette was inserted just upstream of exon 4 and a third loxP site was inserted just downstream. The floxed mutation does not affect the protein expression of the targeted gene in MEF's or mammary tissue from homozygotes. When bred to mice that express Cre recombinase, the resulting offspring will have exon 4 (encoding a conserved Sir2 motif) deleted in the cre-expressing tissue(s). (J:85542, J:121948)
