The transgene minigene contains a 2.9 kb fragment of the promoter the first non-coding exon and intron 1, the remaining coding sequence from exon 2 through 11 with nucleotide substitutions that result in the amino acid substitution of tryptophan for cysteine at position 147 (C147W), and the entire 3'UTR. Line 958 was generated. (J:161532)
