Mutation origin

• Germline Transmission: Earliest citation of germline transmission: J:26748
• Parent Cell Line: E14 (ES Cell)
• Strain of Origin: 129P2/OlaHsd

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutation: Insertion
• Mutation details: The gene was disrupted at codon 370 by insertion of a neomycin resistance cassette into exon 3 via homologous recombination. Absence of gene expression in homozygous mutant animals was demonstrated by Northern blot analysis of liver, spleen, and brain tissues using the full cDNA sequence as a probe. No enzyme activity was detectable in total protein extracts of liver, spleen, and brain from homozygous mutants. (J:26748)
