Transcription factor that binds to the promoter and the enhancer regions of target genes (By similarity). Involved in responding to mitochondrial damage (PubMed:28662060). Has a protective role in response to infection by the Gram-negative bacterium P.aeruginosa (PubMed:28662060). RNAi-mediated knockdown decreases survival upon infection with P.aeruginosa. Belongs to the bZIP family. C/EBP subfamily.
