Protein Structure
UniProt Annotation
Function Transcription factor essential for hepatocyte growth, the differentiation of plasma cells, the immunoglobulin secretion, and the unfolded protein response (UPR). Acts during endoplasmic reticulum stress (ER) by activating unfolded protein response (UPR) target genes via direct binding to the UPR element (UPRE). Binds DNA preferably to the CRE-like element 5'- GATGACGTG[TG]N(3)[AT]T-3', and also to some TPA response elements (TRE) (By similarity). Isoform 2 is involved in controlling the production of interleukin-6. {ECO:0000250, ECO:0000269PubMed:12612580, ECO:0000269PubMed:14559994}.
