Targeted Allele Detail
Symbol: Ightm3.1Cog
Name: immunoglobulin heavy chain complex; targeted mutation 3.1, Michel Cogne
MGI ID: MGI:3522204
Synonyms: delta hs3b4, delta hs3b/hs4, Rr152tm3.1Cog
Gene: Igh  Location: Chr12:113222388-115973574 bp, - strand  Genetic Position: Chr12, Syntenic
Germline Transmission:  Earliest citation of germline transmission: J:71300
Parent Cell Line:  E14 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Modified regulatory region, Null/knockout)
Mutation:    Intragenic deletion
Mutation detailsThis targeted mutation deletes a 6-kilobase genomic DNA segment containing hs3b (Rr155) and hs4 (Rr156), the two most distant of four 3' transcriptional enhancers residing within the approximately 26 kilobase locus control region downstream of the Igh complex (3'RR or Rr152). The original targeting event replaced hs3b and hsb4 with a loxP-flanked neomycin resistance gene cassette. Crossing of chimeric founder mice with mice expressing Cre recombinase under control of the EIIa promoter yielded progeny in which the neo cassette was deleted in the germline. (J:71300)
