Targeted Allele Detail
Symbol: Hoxb1tm1.1Mist
Name: homeobox B1; targeted mutation 1.1, Michele Studer
MGI ID: MGI:5287678
Synonyms: Hoxb1null, Hoxb1 null
Gene: Hoxb1  Location: Chr11:96256578-96259082 bp, + strand  Genetic Position: Chr11, 59.86 cM
Germline Transmission:  Earliest citation of germline transmission: J:82809
Parent Cell Line:  TBV2 (ES Cell)
Strain of Origin:  129S2/SvPas
Allele Type:    Targeted (Modified regulatory region, Null/knockout)
Mutation:    Insertion
Mutation detailsA loxP site was inserted into the Hoxb1 locus upstream of the r4 enhancer. A loxP-flanked neo cassette was inserted into intron 1. Internal to the first two loxP sites, two heterospecific Frt sites were also inserted such that by recombinase mediated cassette exchange, exogenous sequences could be knocked into Hoxb1. Electroporation of a cre-expressing plasmid into an ES cell clone containing the modified locus resulted in excision of the regions between the different combinations of loxP sites. Deletion of the region between the proximal and distal loxP sites produced the Hoxb1null allele. (J:197162)
