Targeted Allele Detail
Symbol: Acetm2Keb
Name: angiotensin I converting enzyme (peptidyl-dipeptidase A) 1; targeted mutation 2, Kenneth E Bernstein
MGI ID: MGI:2155953
Synonyms: ACE.2 KO
Gene: Ace  Location: Chr11:105967945-105989964 bp, + strand  Genetic Position: Chr11, 68.84 cM
Germline Transmission:  Earliest citation of germline transmission: J:40475
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 detailsReplacement of 91bp upstream of the testis specific transcription start site and the first 17bp of the testis specific first exon with a neomycin cassette. All if the somatic coding regions downstream of the neomycin cassette were inserted into intron 12. However, somatic isoforms expressed from this allele do not contain the C-terminal hydrophobic tail. Northern blot and RT-PCR analysis revealed that a cryptic splice site caused a 40bp insertion into the transcript and introduced an in frame stop codon. Western blot and activity assays demonstrated an absence of protein in tissues of homozygous mice. (J:40475)
