Germline Transmission:  Earliest citation of germline transmission: J:25511
Parent Cell Line:  AB2.1 (ES Cell)
Strain of Origin:  129S7/SvEvBrd-Hprtb-m2
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA neomycin selection cassette replaced a genomic fragment containing 585 bp of the promoter and exons 1-4. Northern blot analysis on RNA derived from various tissues of homozygous mice demonstrated that no detectable transcript was produced from this allele. However, a transcript has been reported from sequence downstream from exon 4. (J:25511, J:53925)
