Targeted Allele Detail
Symbol: Tnftm2Gkl
Name: tumor necrosis factor; targeted mutation 2, George Kollias
MGI ID: MGI:2388715
Synonyms: TNFdeltaARE
Gene: Tnf  Location: Chr17:35418357-35420983 bp, - strand  Genetic Position: Chr17, 18.59 cM
Germline Transmission:  Earliest citation of germline transmission: J:54056
Parent Cell Line:  CCE/EK.CCE (ES Cell)
Strain of Origin:  129S/SvEv-Gpi1c
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation details69 bp encompassing the AU-rich elements (ARE) were deleted by homologous recombination of a floxed neo cassette and subsequent in vitro cre mediated excision. The resultant allele contained a single loxP site in place of the ARE sequence. ELISA of homozygous mutant mice showed protein levels higher than in wild-type mice, indicating a suppressive role of the AREs. (J:54056)
