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 detailsThe Dad1 locus was disrupted by the insertion of a neomycin selection cassette that replaced exon 3 of Dad1 and the Tcra associated DNAse I hypersensitive sites 2 through 6. Neither Dad1 transcript nor protein was detected in homozygous mutant mice by RNAse protection or Western blot analyses. Expression analysis showed the deleted hypersensitive sites were necessary for the enhancement of Tcra transcription in a fraction of immature T cells. (J:77517, J:77676)
