• Mutation details: First, the human tropomyosin 3 gene was used to isolate a full-length alphaTm^slow cDNA sequence. Next, the sequence was modified by site-directed mutagenesis to have the ATG-to-AGG base pair substitution encoding a methionine-to-arginine substitution at codon 9 (M9R); resulting in the dominant-negative alphaTm^slow(Met9Arg) mutation associated with human nemaline myopathy. The mutant cDNA sequence was placed downstream of a 2.2 kbp human alpha-skeletal actin (ACTA1) promoter sequence, and upstream of a 1022 bp cassette containing the SV40 small t antigen intron and 3' untranslated region. Lines 4, 9 and 14 were generated with high, low and moderate expression levels, respectively. (J:67596)
