Name: potassium voltage-gated channel, subfamily H (eag-related), member 2; targeted mutation 1, Henry J Duff
MGI ID: MGI:2652959
Synonyms: ERG1 B-
Gene: Kcnh2  Location: Chr5:24319589-24351604 bp, - strand  Genetic Position: Chr5, 10.94 cM
Germline Transmission:  Earliest citation of germline transmission: J:82249
Parent Cell Line:  R1 (ES Cell)
Strain of Origin:  (129X1/SvJ x 129S1/Sv)F1-Kitl+
Allele Type:    Targeted (Null/knockout)
Mutations:    Insertion, Intragenic deletion
Mutation detailsAn isoform specific mutation was generated by replacing the coding region of exon 1B with a floxed neomycin selection cassette. RT-PCR analysis verified that sequence upstream of the insertion, encoding the A isoform, was transcribed. Transcript encoding the B isoform was undected in homozygous mutant mice by RT-PCR analysis.
