WebOct 31, 2013 · Ire1 Signaling Is Activated in the Photoreceptors during Pupal Stages To detect Ire1 signaling activity in the photoreceptors during development, we used the Xbp1-EGFP reporter ( Ryoo et al., 2007 ), in which EGFP becomes in frame with Xbp1 only upon Ire1-dependent mRNA splicing. WebMar 31, 2024 · IRE1 is an unfolded protein response (UPR) sensor with kinase and endonuclease activity. It plays a central role in the endoplasmic reticulum (ER) stress …
Role of Endoplasmic Reticulum Stress Sensor IRE1α in Cellular
WebJun 24, 2015 · Based on the evidence that Ire1 directly cleaves RIDD targets in their Xbp1-like SLs, we wondered whether reduced ribosome occupancy in this specific region, rather than the entire message, is important for RIDD. ... Xbp1-independent Ire1 signaling is required for photoreceptor differentiation and rhabdomere morphogenesis in Drosophila. ease reference
Pumilio protects Xbp1 mRNA from regulated Ire1-dependent decay
WebFeb 4, 2024 · IRE1 is a transmembrane protein composed of three distinct domains, a sensing domain in the ER lumen, connected through a transmembrane segment to a cytosolic regulatory kinase domain, and finally a C-terminal RNase domain. WebFeb 1, 2016 · Rapid downregulation of pathogenesis-related (PR) gene expression in an OsIRE1 RNase-dependent manner. Quantitative reverse transcription (RT)-PCR analyses of the expression levels of a candidate regulated IRE1-dependent decay (RIDD) target mRNA (Os03 g0663400) in rice plants (Oryza sativa). (a) Time-course analyses of the expression … WebAug 23, 2024 · Besides of XBP1 pre-mRNA, RNase activity of IRE1α also mediates the degradation of a select subset of cellular mRNAs, that is termed regulated IRE1-dependent decay (RIDD) . RIDD cleaved pre-mRNAs at a site different from the XBP1 spliced site, and either maintains ER homeostasis or induces apoptosis [ 21 ]. ct to philly
