后续的研究证明,QRICH1是属于UPR PERK-eIF2a通路的关键效应因子,其翻译受到QRICH1 mRNA上游开放阅读框的调控。 通过结合RNA-seq和染色质免疫沉淀测序 (ChIP-seq)的结 …
eIF2α phosphorylation is pathognomonic for immunogenic cell …
2018年1月22日 · Active IRE1 possesses in its cytoplasmic domain an endoribonuclease function allowing it to excise an intron of 26 nucleotides from the mRNA of the transcription factor X …
The eIF2 kinase PERK and the integrated stress response ... - PubMed
Three ER stress sensors (PERK, ATF6, and IRE1) implement the UPR. PERK phosphorylation of the α subunit of eIF2 during ER stress represses protein synthesis, which prevents further …
Novel mechanism of enhancing IRE1α-XBP1 signalling via the …
2016年4月7日 · In this study, we found that IRE1α was induced by ER stress both in vivo and in cultured cells. Using various knockout cells, we revealed that the increase in IRE1α …
To prevent a further increase in protein-folding demand in the ER, PERK tran-siently inhibits general protein translation through phos-phorylation of eukaryotic initiation factor 2 alpha …
Role of eIF2α Kinases in Translational Control and Adaptation to ...
Key themes in the review will be the mechanisms regulating eIF2α kinases, the role that upstream open reading frames (uORFs) play in translational control, and the impact that altered P-eIF2α …
