Targeted Allele Detail
Symbol: Mmuttm1Pai
Name: methylmalonyl-Coenzyme A mutase; targeted mutation 1, Panayiotis A Ioannou
MGI ID: MGI:3026839
Synonyms: mut-
Gene: Mmut  Location: Chr17:40934685-40961988 bp, + strand  Genetic Position: Chr17, 19.55 cM, cytoband C-D
Germline Transmission:  Earliest citation of germline transmission: J:87081
Parent Cell Line:  W9.5/W95 (ES Cell)
Strain of Origin:  129S1/Sv-Oca2+ Tyr+ Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsExon 3 was replaced with neomycin/kanamycin cassette inserted by homologous recombination. The deleted region encoded residues 126 through 251 which make up a portion of the CoA and cobalamin binding domains. Transcript was undetected in homozygous mutant mice by RT-PCR analysis of hepatic RNA. [14C]propionate incorporation in primary fibroblast cultures from mutant mice revealed that enzyme activity was reduced to ~6% of wild-type levels. (J:87081)
