Probable transcription factor (PubMed:26438299). Modulates lifespan and also recovery from the developmentally arrested larval state known as dauer, perhaps acting upstream of phosphatase PTEN/daf-18 (PubMed:26438299). Regulates expression of genes involved in cell division, cell-cycle regulation, and sexual reproduction, including daf-18 (PubMed:26438299). Expressed postembryonically at all larval and adult stages, including the developmentally arrested larval state known as dauer stage (PubMed:26438299). Expressed in neurons of the head and tail, including the motor neurons VD1, DA3, and DA7 (PubMed:26438299). Also expressed in the anal depressor muscle, anterior and posterior intestinal cells, and the head and body wall muscles (PubMed:26438299). Expressed in the PDE sensory neuron pairs and rare, transient expression seen in migrating distal tip cells of larval L3/L4 stages (PubMed:26438299). Hermaphrodites produce fewer live progeny at 20 degrees Celsius than wild-type, and also laying more unfertilized oocytes throughout the egg-laying period (PubMed:26438299). Abnormal gonad morphology (PubMed:26438299). Delayed recovery from the developmentally arrested larval state known as dauer (PubMed:26438299). Significantly longer lifespan (PubMed:26438299). Decreased movement (PubMed:26438299). RNAi-mediated knockdown causes an increase in daf-18 transcripts (PubMed:26438299).
