Enzyme Function FUNCTION: Transcription factor required to specify the fate of ventral blastomeres in the early embryo, and postembryonically for the development of the intestine. Directly regulates expression of zygotically expressed med-1 and med-2 to direct mesendoderm development (PubMed:1547503, PubMed:11463373). Required for stl-1 mRNA up-regulation in response to oxidative stress and anoxia. Required for the up-regulation of gcs-1 and several glutathione-S-transferase mRNAs in response to oxidative stress generated during pathogenic bacterial infection (PubMed:22216003). Modulates oxidative stress responses in concert with transcriptional coregulator hcf-1 (PubMed:22568582). Regulates the transcription of genes associated with metabolism in response to changes in nutrient availability (PubMed:23040073). In neurons, involved in mitochondrial fusion and behavioral recovery during reoxygenation (PubMed:24385935). Required for riok-1 mRNA expression in the intestine (PubMed:25688864). Downstream of the let-60/Ras, mek-2 and pmk-1 pathway, positively regulates lifespan probably by preventing transcription of insulin-like peptides such as ins-39 (PubMed:20624915). Prevents degeneration of dopaminergic CEP neurons in response to high Al(3+) or Mn(2+) levels, probably by promoting the expression of glutathione-S-transferase gst-1 (PubMed:23106139, PubMed:23721876). {ECO:0000269|PubMed:11463373, ECO:0000269|PubMed:1547503, ECO:0000269|PubMed:20624915, ECO:0000269|PubMed:22216003, ECO:0000269|PubMed:22568582, ECO:0000269|PubMed:23040073, ECO:0000269|PubMed:23106139, ECO:0000269|PubMed:23721876, ECO:0000269|PubMed:24385935, ECO:0000269|PubMed:25688864}.; FUNCTION: [Isoform a]: Directed by the ER-associated degradation pathway (ERAD), mediates proteasomal homeostasis by regulating the expression of proteasomal subunits such as rpt-3 to confer resistance to proteasomal dysfunction. {ECO:0000269|PubMed:27528192}.

Note=In absence of stress, localizes in the cytoplasm of intestinal cells (PubMed:16166371, PubMed:22216003, PubMed:26920757). Upon paraquat or arsenite treatments or upon bacterial infection, localizes in the nucleus (PubMed:16166371, PubMed:22216003, PubMed:26920757). Nuclear localization is regulated by pmk-1-mediated phosphorylation (PubMed:16166371, PubMed:26920757). Nuclear localization is regulated by transcriptional coregulator hcf-1. {ECO:0000269|PubMed:16166371, ECO:0000269|PubMed:22216003, ECO:0000269|PubMed:22568582, ECO:0000269|PubMed:26920757}.; SUBCELLULAR LOCATION: [Isoform a]: Nucleus {ECO:0000269|PubMed:27528192}. Mitochondrion {ECO:0000269|PubMed:23040073}. Note=Localizes to the nucleus in response to proteasomal dysfunction. {ECO:0000269|PubMed:27528192}.
