BRC No.RBRC02421
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameC.Cg-Bcl11b<tm1Jpk>
Former Common nameBcl11b/Rit1-KO mice
H-2 Haplotype
ES Cell lineTT2 [(C57BL/6NCrlj x CBA/JNCrlj)F1]
Background strain
Appearancealbino [A/A b/b c/c]
Strain developmentDeveloped by Ryo Kominami, Graduate School of Medical and Dental Science, Niigata University. TT2 ES cells derived from B6CBAF1 were used for the generation of knockout mice. C57BL/6 background (RBRC06231), BALB/c background (RBRC02421).
Strain descriptionBcl11b gene knock-out mice. A PGK-neo cassette was inserted into exon 1 of the Bcl11b gene. Bcl11b is a tumor-suppressor gene involved in T cell lymphomas. Homozygous mutant mice diw within the first day after birth. Mutant mice show a block at the CD4-CD8 double-negative stage of thymocyte development without any impairment in cells of B- or gammadelta T cell lineages. C57BL/6 background (RBRC06231), BALB/c background (RBRC02421).
Colony maintenanceHeterozygote x Wild-type [BALB/cAJcl]
