Function
Transcription activator involved in the regulation of genes expressed in response to environmental changes and metabolic requirements. According to genome-wide promoter binding and gene expression studies it regulates, among others, genes involved in ribosome biogenesis, and protein synthesis. It may also be involved in pleiotropic drug resistance. When overexpressed it confers increased resistance to cisplatin, the DNA-alkylating agents methylmethanosulfonate, and mitomycin C, the antimalarial drugs quinidine, mefloquine, and chloroquine, and increases cellular tolerance to sodium and lithium. Preferentially binds 5'-TTACTAA-3'.
