Transcription factor (By similarity). Plays a role in regulating the developmentally arrested larval state known as dauer, when induced by long-term exposure to the Gram-negative bacterium P.aeruginosa PAO1, but dispensable for dauer formation induced by starvation (PubMed:32963007). Involved in regulating expression of microRNA mir-243, during long-term exposure to P.aeruginosa PAO1 (PubMed:32963007). Expression up-regulated in animals exposed to the Gram-negative bacterium P.aeruginosa PAO1 for two generations. Belongs to the bZIP family.
