Mutation description

• Allele Type: Targeted (Conditional ready)
• Mutation: Insertion
• Mutation details: An arginine to cysteine substitution at amino acid 117 was knocked-in using the FLEx switch system. A cassette containing the following elements replaced the wild-type exon 7: a loxP site, a loxP511 site, exon 7 with a mutation changing arginine codon 117 (CGC) to cysteine (TGC) (p.R117C) in reverse orientation, an FRT site flanked neomycin selection cassette, a loxP site in reverse orientation, wild-type exon 7 in forward orientation, and a loxP511 site in reverse orientation. Upon expression of Cre recombinase, the wild-type exon 7 will be removed and the mutated exon, harboring the R117C missense mutation, will be flipped to the forward orientation. (J:325969)
