Mutation description

• Allele Type: Targeted (Conditional ready, Dominant negative)
• Mutation: Nucleotide substitutions
• Mutation details: The open reading frame was replaced with a construct containing a 5' floxed neo cassette, a cDNA encoding the Thra open reading frame with a nucleotide substitution that results in an amino acid substitution of arginine for leucine at position 400 (L400R), and a 3' IRES-Tau-lacZ cassette. The L400R mutation is thought to place the receptor in an unliganded state and create a dominant negative receptor. Expression of the mutant receptor and lacZ is only achieved by cre-mediated removal of the floxed neo cassette. Western blot analysis was used to confirm expression of the mutant receptor following cre-mediated recombination. (J:125353)
