Functional analysis of putative transcription factor binding sites in the MTG16 promoter. Putative Sp1 (-425), GATA (-301) and MZF-1 (-251) sites in the -668-57 (-668) promoter were individually destroyed by site directed mutagenesis as decribed in Methods. Erythroid HEL/TF-1, erythroid/megakaryocytic UT-7 and megakaryocytic MEG-01cells were transfected and luciferase activity was determined. The pGL3/basic and pGL3/SV40-promoter are used as negative and positive control, respectively. The luciferase activity of mutated MTG16 promoter is normalized against luciferase activity of wildtype MTG16 promoter.
