Transcription factor (By similarity). Involved in positively modulating longevity and stress tolerance, probably acting by positively regulating expression of transsulfuration enzyme cth-2, leading to increased hydrogen sulfide production and therefore increased protein persulfidation, a protective modification of redox-reactive cysteines (PubMed:35181679). May mediate longevity and increased stress resistance induced by mTORC1 suppression (PubMed:35181679). Expressed at steady levels during development and aging. Positively modulated by global suppression of translation activated via integrated stress response. RNAi-mediated knockdown abrogates an increase in hydrogen-sulfide production in an mTORC2 subunit rict-1 mutant background. Belongs to the bZIP family.
