Probable transcription factor (PubMed:20938051, PubMed:24834345). Plays a role in regulating heme-dependent expression of heme transporter hrg-1 (PubMed:20938051). Modulates lifespan in a daf-16-dependent manner (PubMed:24834345). Expressed at the 1.5-fold stage of embryogenesis and by the 3-fold stage, in all cells of the gut (PubMed:14573471). Expressed in nine cells in the posterior bulb of the pharynx from the 3-fold stage (PubMed:14573471). Expressed in the intestine at all stages of development (PubMed:14573471). No phenotype detected and so may be dispensable (PubMed:14573471). RNAi-mediated knockdown causes intestinal expression of heme transporter hrg-1 induced by heme to be reduced drastically in L3 stage larvae (PubMed:20938051). Reduces expression of the daf-16 isoforms d and f (PubMed:24834345).
