Protein kinase CK2 in the ER stress response
نویسندگان
چکیده
The endoplasmic reticulum is the central organelle within a eukaryotic cell where newly synthesized proteins are processed and properly folded. An excess of unfolded or mis-folded proteins induces ER stress signalling pathways. Usually this means a pro-survival strategy for the cell, whereas under extended stress conditions the ER stress signalling pathways have a pro-apoptotic function. CK2 plays a key role in the regulation of the pro-survival as well as the proapoptotic ER stress signalling by directly modulating the activities of members of the ER stress signalling pathways by phosphorylation, regulating the expression of the key factors of the signalling pathways or binding to regulator proteins. The present review will summarize the state of the art in this new emerging field.

Stress signals cause abnormal proteins to accumulate in the endoplasmic reticulum (ER). Such stress is known as ER stress, which has been suggested to be involved in neurodegenerative diseases, diabetes, obesity and cancer. ER stress activates the unfolded protein response (UPR) to reduce levels of abnormal proteins by inducing the production of chaperon proteins such as GRP78, and to attenuate...

Background: Recently, it has been revealed that tyrosine kinase inhibitors (TKIs) act through inducing both oxidative and endoplasmic reticulum (ER) stress in chronic myeloid leukemia cells. However, ER stress signaling triggers both apoptotic and survival processes within cells. Nevertheless, mechanisms by which TKIs avoid the pro-survival effects are not clear. The aim of this study was to ev...

Protein kinase CK2 is a critical factor for the survival of cells. It is overexpressed in many cancer cells and provides protection against apoptosis in these cells. Inhibition of CK2 kinase activity in various cancer cells leads to apoptosis, which makes CK2 an attractive target for cancer therapy. Little is, however, known about CK2 inhibition in non-cancerous cells. Using the human retinal p...

Purpose: Protein kinase CK2 promotes multiple myeloma cell growth by regulating critical signaling pathways. CK2 also modulates proper HSP90-dependent client protein folding and maturation by phosphorylating its co-chaperoneCDC37. Because the endoplasmic reticulum(ER) stress/unfoldedprotein response (UPR) is central in myeloma pathogenesis, we tested the hypothesis that the CK2/CDC37/HSP90 axis...
متن کاملProtein kinase CK2 regulates the formation and clearance of aggresomes in response to stress.
Misfolded protein aggregates elicit a stress response, and their clearance is crucial for cell survival. These aggregates are transported by cytoplasmic deacetylase HDAC6 and dynein motors to the aggresome via the microtubule network, and are removed by autophagic degradation. HDAC6 activity is necessary for both the transport and clearance of protein aggregates. However, the cellular factors t...
