Background
CHOP (C/EBP-homologous protein, DDIT3) belongs to C/EBP transcription-factor family and governs endoplasmic-reticulum-stress-dependent apoptosis. Under physiological conditions, CHOP remains barely detectable. Upon ER stress, PERK-eIF2α pathway strongly up-regulates CHOP transcription. As a transcription factor, CHOP remodels downstream gene expression, represses anti-apoptotic Bcl-2 and activates pro-apoptotic programs to trigger ER-stress-induced cell death. Sustained ER stress causes massive CHOP accumulation and cell injury, contributing to metabolic disorders, neurodegeneration and tumor drug resistance.
