Activation of the Transducers of Unfolded Protein Response in Plants
Maintenance of homeostasis of the endoplasmic reticulum (ER) ensures the balance between loading of nascent proteins and their secretion. Certain developmental conditions or environmental stressors affect protein folding causing ER stress. The resultant ER stress is mitigated by upregulating a set of stress-responsive genes in the nucleus modulating the mechanism of the unfolded protein respons...
متن کاملActivation of the unfolded protein response in aged human lenses.
Cataract formation is a multifactorial disease, induced by a variety of stressors. The endoplasmic reticulum (ER) stress-induced unfolded protein response (UPR) is known to produce reactive oxygen species (ROS) leading to apoptosis. The present study aimed to investigate whether activation of the UPR occurs in human lenses, using human lens epithelial cell (HLEC) lines and lenses obtained from ...
متن کاملActivation of an unfolded protein response during differentiation of antibody-secreting B cells.
The unfolded protein response pathway (UPR) is believed to detect and compensate for excessive protein accumulation in the endoplasmic reticulum (ER). The UPR can be induced by pharmacological agents that perturb ER functions, but may also occur during cellular developmental processes such as the transition of B-lymphocytes into antibody-secreting plasma cells. Here we show that major UPR compo...
متن کاملThe unfolded protein response
Where does the UPR function? Between the endoplasmic reticulum (ER) and the nucleus of eukaryotic cells. All secreted proteins and proteins that reside in secretory compartments translocate as nascent peptide chains into the ER, where they may undergo folding, modification and assembly before assuming their functional conformations. The ER maintains a specialized oxidizing environment to aid ch...
متن کاملThe unfolded protein response.
The endoplasmic reticulum (ER) is a principal site for folding and maturation of transmembrane, secretory and ERresident proteins. Perturbations that alter ER homeostasis can lead to accumulation of unfolded proteins (UPs), which is a threat to all living cells. To cope with the stress, cells activate an intracellular signaling pathway – the unfolded protein response (UPR). The UPR is an integr...
