Identification of putative PPREs in promoter of NHE1 and MnSOD. (A) Human NHE1 promoter sequence from NCBI and Ensembl (Sequence IDs indicated). Alu element underlined, with putative PPREs italicized and bold. Transcriptional start site (T) and ATG translational start codon shown in figure. (B) We predicted two PPREs with PPARγ binding efficiencies indicated.
