LoxP sites were inserted, with an adjacent FRT flanked neomycin resistance cassette, upstream and downstream of exon 4. Mice were subsequently mated to flp expressing mice and the offspring mated to cre expressing mice to delete, first, the selection cassette, and then exon 4. Quantitative RT-PCR from mouse brain confirmed decreased mRNA. Immunological studies confirmed the absence of protein product in the brain. (J:194266)
