Mutants of the −2084/−2078 motif in ABCA12 show striking reduction of promoter activity.
Three different mutants of the −2084/−2078 motif were generated using the −2980/+190 fragment as a template and the promoter activity of each fragment was assessed. The mutants lacked 1–3 bases from the wild-type sequence (tgagtca): mutant Δ1 (tga-tca), mutant Δ2 (tga--ca) and mutant Δ3 (tg---ca). The promoter activities of the mutants were compared to that of the wild type. *P < 0.01 compared with the wild type.
