Cremer et al. show that the ubiquitin ligase RNF26 and vimentin-based intermediate filaments cooperate to control perinuclear ER membrane organization and thus facilitate recovery from ER stress.
To activate noncanonical LC3B lipidation and NLRP3 inflammasome formation, stimulator of interferon genes (STING) forms a proton channel in Golgi membranes.
In the amphibian axolotl, the kinase mTOR is hyper-sensitive and activates a protein synthesis response that is crucial for wound healing and tissue regeneration.
Single-cell multi-omics methods are essential for characterizing cell states and types. The past decade has ushered in improvements in spatial resolution and computational data integration and in new omics modalities. Consequently, single-cell multi-omics have advanced fundamental and translational research, including, for example, in production of cell atlases and in tumour immunology therapeutics.
Nucleobase modifications are prevalent in eukaryotic mRNA and are broadly required for post-transcriptional gene regulation. The most studied mRNA modification is N6-methyladenosine (m6A), yet various other modifications are now being identified and studied. This Review discusses the emerging mechanisms and roles of these non-m6A modifications.
BCL-2 proteins fulfil important functions in cell death as initiators, guardians and executioners of mitochondrial outer membrane permeabilization. Recent findings demonstrating complex interactions among BCL-2 proteins set forth a comprehensive model of BCL-2 action.
All aspects of gene regulation involve RNA helicases, which bind or remodel RNA and RNA–protein complexes. Recent data establish a link between helicase structure, mechanism of function and biological roles, including in diseases such as cancer and neurological disorders, with implications for the design of small-molecule inhibitors.
