Targeted Allele Detail
Symbol: Insrtm1Khn
Name: insulin receptor; targeted mutation 1, Ronald Kahn
MGI ID: MGI:2384332
Synonyms: Insrflox, IRflox, IRlox, IR(lox), IRLox
Gene: Insr  Location: Chr8:3150922-3279649 bp, - strand  Genetic Position: Chr8, 1.82 cM
Germline Transmission:  Earliest citation of germline transmission: J:51266
Parent Cell Line:  J1 (ES Cell)
Strain of Origin:  129S4/SvJae
Allele Type:    Targeted (Conditional ready, No functional change)
Mutation:    Insertion
Mutation detailsExon 4 was left flanked by single loxP sites after a downstream floxed neo cassette was removed via in vitro cre mediated recombination. Deletion of the resultant floxed fragment will result in a frameshift mutation that introduces a stop codon. Translation, if it were to occur, would putatively produce a truncated peptide consisting of 308 amino terminal residues and lacking the high affinity binding site, transmembrane domain, and kinase domain.

In conjunction with Tg(Mycha-cre)1Abel, this allele is knocked out specifically in cardiac muscle. The resulting mice are referred to as "Cardiac-specific insulin receptor knockout mice" or CIRKO.

In conjunction with Tg(Ckmm-cre)5Khn, this allele is disrupted specifically in skeletal muscle. The resulting mice are referred to as "Muscle-specific insulin receptor knockout mice" or MIRKO.
