Germline Transmission:  Earliest citation of germline transmission: J:29269
Parent Cell Line:  AB1 (ES Cell)
Strain of Origin:  129S7/SvEvBrd-Hprt+
Allele Type:    Targeted (Null/knockout)
Mutation:    Insertion
Mutation detailsA neomycin cassette was inserted into exon 3 (codon 40 of the 439 codon reading frame) of the gene. This insertion truncated the peptide 13 amino acid residues downstream of the cleavage site for the N-terminal mitochondrial targeting sequence. Southern blots showed production of a truncated protein in mutant mice, and functional assasys showed lack of enzymatic activity of the truncated protein. (J:29269)
