Germline Transmission:  Earliest citation of germline transmission: J:84747
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Inducible, Recombinase)
Inducer:    tamoxifen
Mutation:    Insertion
Mutation detailsA cDNA fragment encoding a fusion protein comprised of cre recombinase and the ligand binding domain of Esr1 was inserted at the endogenous locus via homologous recombination. The initiator methionine was placed in an optimal translational context, allowing for near ubiquitous expression via the endogenous promoter. Activation of cre recombinase activity is dependent on the administration of 4-HO-tamoxifen. (J:84747)
