Nucleotide sequence of the promoter region of ProDH. Underlines show the putative TATA box (TATAA), G-box-like sequence (ACGTG), MYB recognition site (PyAACNPu), MYC recognition site (CANNTG), and as-1 sequence (TGACG). ▪, The direct repeat sequence ACTCATCCT. ▴, Start points of 5′-deleted derivatives. The nucleotide sequence was analyzed with the Genetyx software system (Software Development, Tokyo).
