Sequence elements similar to those identified in the BAG1 and B-NTPase promoters can be found in the genomic regions important for bradyzoite induction of the LDH2, SAG4.2 and 65 kDa cyst wall promoters (Fig. S4), although mutations in these sequence elements have not yet been functionally tested using the dual luciferase assay. This evidence concerns the gene BAG1 and cyst.
