ATP enters the endoplasmic reticulum (ER) lumen through an SLC35B1/AXER-dependentCaATiER mechanism, and ATP usage in the ER renders 'anti-Warburg' effect by increasing ATP regeneration from OxPhos while decreasing glycolysis.
Human ferritin light chain (FTL) mRNA translation is regulated via its 5'-untranslated region (5'-UTR) by three mechanisms: RNA folding, iron response protein binding, and eukaryotic translation initiation factor eIF3 binding.
Biochemical and biological studies reveal that caspases feed back onto the Unfolded Protein Response by cleaving the ER-stress sensor IRE1 to produce a cytoprotective N-terminal fragment that inhibits BAX-dependent apoptosis.
OptoGranules reveal the function of G3BP1 as a stress granule scaffold and demonstrate that protracted stress granule assembly is sufficient to drive neurodegeneration and the evolution of ALS-FTD pathology.
The molecular microenvironment of coronaviral replicase complexes provides functional and spatial links between conserved cellular processes and viral RNA synthesis, and highlights potential targets for the development of novel antivirals.
