Targeted Allele Detail
Symbol: Sirt1tm1.1Ygu
Name: sirtuin 1; targeted mutation 1.1, Yansong Gu
MGI ID: MGI:3713747
Synonyms: SIRT1-, SirT1ko
Gene: Sirt1  Location: Chr10:63319005-63339035 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 (Null/knockout)
Mutations:    Insertion, Intragenic deletion
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. Exon 4 (encoding a conserved Sir2 motif) was then removed by cre-mediated recombination to create a null allele. Absence of protein product was confirmed by western blot analysis. (J:121948)
