Targeted Allele Detail
Symbol: Spibtm1Mcs
Name: Spi-B transcription factor (Spi-1/PU.1 related); targeted mutation 1, M Celeste Simon
MGI ID: MGI:2448991
Synonyms: Spi-B-
Gene: Spib  Location: Chr7:44525993-44532071 bp, - strand  Genetic Position: Chr7, 28.83 cM
Germline Transmission:  Earliest citation of germline transmission: J:45245
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 gene was disrupted by replacement of the DNA-binding domain-containing exon 6 and part of intron 5 with a PGK-neo cassette via homologous recombination. Northern blot analysis of homozygous mutant splenocyte RNA (using a full-length Spib cDNA probe) confirmed the absence of gene expression. (J:45245)
