• Germline Transmission: Earliest citation of germline transmission: J:89778
• Parent Cell Line: E14TG2aIV (ES Cell)
• Strain of Origin: 129P2/OlaHsd

Mutation description

• Allele Type: Targeted (Null/knockout)
• Mutations: Insertion, Intragenic deletion
• Mutation details: A STOP codon and coding sequence for haemaglutinin (HA) epitope tag were inserted in frame before the start of the GK domain at amino acid 500. In addition, a floxed neo cassette was inserted downstream to replace sequence and this cassette was subsequently excised by Cre leaving a single loxP site after the STOP codon. Western blot and immunoprecipitation analysis confirmed the absence of protein in hippocampal extracts from homozygous mice. RT-PCR analysis indicated that a very low level of mRNA expression (less than 5% of wild-type) was present in hippocampal extracts from homozygous mice. (J:149508)
