Luman is capable of binding and activating transcription from the unfolded protein response element.
Luman (or LZIP, CREB3) is a transcription factor with an endoplasmic reticulum (ER)-transmembrane domain. Due to its structural similarities with ATF6, it is thought that Luman might also be involved in cellular stress responses. Here we report that Luman can bind and activate transcription from the consensus unfolded protein response element (UPRE). Mutations that disrupted the binding of Luma...
Mammalian inositol-requiring enzyme 1α (IRE1α) is the most conserved of all endoplasmic reticulum (ER) stress sensors, which includes activating transcription factor (ATF) 6 and double-stranded RNA-dependent protein kinase (PKR)-like ER kinase (PERK). IRE1α has been known to splice X-box binding protein 1 (XBP1) mRNA, which is induced by ATF6 under ER stress. This spliced XBP1 mRNA is translate...
The unfolded protein response is an adaptive stress response that responds to the imbalance between the entry of newly synthesized unfolded proteins and the inherent folding capacity in the endoplasmic reticulum (ER). Various environmental stresses and changes in physiological conditions can result in the accumulation of unfolded proteins in the ER, which is sensed through ER transmembrane prot...
Endoplasmic reticulum (ER) stress activates a set of signaling pathways, collectively termed the unfolded protein response (UPR). The three UPR branches (IRE1, PERK, and ATF6) promote cell survival by reducing misfolded protein levels. UPR signaling also promotes apoptotic cell death if ER stress is not alleviated. How the UPR integrates its cytoprotective and proapoptotic outputs to select bet...
