Strain Data Sheet



BRC No.RBRC10756
TypeTargeted MutationCartagena
SpeciesMus musculus
Strain nameB6.129-Mab21l1<tm1Nao>
Former Common nameC57BL/6(Mab21l1tm1Nao), Mab21l1tm1Nao
H-2 Haplotype
ES Cell lineR1 [(129X1/SvJ x 129S1/Sv)F1-Kitl<+>]
Background strain
Strain developmentR1 ES cells were established in August 1991 from a male blastocyst hybrid of two 129 substrains (129X1/SvJ and 129S1/SV-+p+Tyr-c Kitl Sl-J/+).abnormal male preputial gland morphology abnormal eye morphology abnormal skull development
Strain descriptionThis gene is similar to the MAB-21 cell fate-determining gene found in C. elegans. It may be involved in eye and cerebellum development.Mutation details: The entire gene coding region was replaced with a neomycin resistance cassette via homologous recombination. Absence of gene expression in homozygous mutants was confirmed by whole mount in situ hybridization analysis of E10.5 homozygous mutant embryos.
