Targeted Allele Detail
Symbol: Gcktm1Efr
Name: glucokinase; targeted mutation 1, Shimon Efrat
MGI ID: MGI:1861929
Synonyms: GK-
Gene: Gck  Location: Chr11:5900820-5950081 bp, - strand  Genetic Position: Chr11, 3.88 cM
Germline Transmission:  Earliest citation of germline transmission: J:28756
Parent Cell Line:  E14 (ES Cell)
Strain of Origin:  129P2/OlaHsd
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsA fragment of the gene spanning exon 2 was replaced by a neomycin resistance cassette, resulting in a deletion and a frame shift of the transcript. Mice heterozygous for the targeted mutation had a 37% reduction in glucose phosphorylation activity in islet homogenates and a 28% reduction of activity in liver compared with wild-type littermates.
