XBP1 and infection: Other proteins regulating transcription of infection and stress-modulated genes have been identified, including cyclic AMP-dependent transcription factor-7 (ATF-7), forkhead box O (FOXO) ortholog DAF-16, GATA transcription factors (ELT-2, ELT-3), helix loop helix-30 (HLH-30), heat-shock factor-1 (HSF-1), NF-E2-related factor SKN-1, signal transducer and activator of transcription STA-2, X-box binding protein-1 (XBP-1), and basic leucine zipper domain transcription factor ZIP-2 (Kim and Ewbank, 2015).
