Targeted Allele Detail
Symbol: Mybl2tm1Sis
Name: myeloblastosis oncogene-like 2; targeted mutation 1, Shunsuke Ishii
MGI ID: MGI:2445746
Synonyms: B-myb-
Gene: Mybl2  Location: Chr2:163054687-163084688 bp, + strand  Genetic Position: Chr2, 84.0 cM
Germline Transmission:  Earliest citation of germline transmission: J:57999
Parent Cell Line:  TT2 (ES Cell)
Strain of Origin:  (C57BL/6NCrlj x CBA/JNCrlj)F1
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExon 5, which encodes amino acids 94 through 167, was replaced by the insertion of a neomycin selection cassette. The deleted region encompassed portions of repeats 2 and 3 that are involved in DNA binding. Whereas this allele was observed to be homozygously lethal, similar amounts of protein were detected by Western blot analysis of wild-type and heterozygous mice. (J:57999)
