BRC No.RBRC01767
TypeTargeted Mutation CongenicCartagena
SpeciesMus musculus
Strain nameB6.129S4-Tob1<tm1Tya> Tob2<tm1Tya>/TyaRbrc
Former Common nametob and tob2 KO (B6)
H-2 Haplotype
ES Cell line
Background strainC57BL/6
Strain developmentDeveloped by Dr. Tetsuo Noda, Japanese Foundation for Cancer Research Cancer Institute at and Dr. Tadashi Yamamoto at the University of Tokyo. This strain was produced by crossing Tob1 KO mice and Tob2 KO mice.
Strain descriptionTob is a member of antiproliferative protein family which is a negative regulator BMP/Smad signaling in osteoblasts. Tob1 null mice are viable and exhibit bone mass due to increased numbers of osteoblasts. While, Tob2 null mice appear normal. This strain is useful for elucidating of Tob gene function.
Colony maintenanceBackcross to C57BL/6 (Heterozygote x C57BL/6JJcl)
