AP-1-like transcription factor

UniProtKB accession:  Q01663

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Transcription activator involved in multidrug resistance, oxidative stress response, and redox homeostasis. Regulates the transcription of genes encoding antioxidant enzymes like catalase ctt1 and components of the cellular thiol-reducing pathways, including the thioredoxin system (trx2, trr1), ABC transporters involved in multidrug resistance like bfr1/hba2 and pmd1 as well as the gene obr1/apt1. Preferentially binds to promoters with the core binding site 5'-TTA[CG]TAA-3'. Activity of the transcription factor is controlled through oxidation of specific cysteine residues resulting in the alteration of its subcellular location. Oxidative stress induces nuclear accumulation and as a result pap1 transcriptional activity. Required for sty1/spc1-conferred staurosporine resistance.
