- Robust repression of tRNA gene transcription during stress requires protein arginine methylation
This work examines how protein arginine methylation of Rpc31, a subunit of RNA Pol III, promotes negative regulation of tRNA biogenesis in the context of cellular stress.
- Opposing functions of F-BAR proteins in neuronal membrane protrusion, tubule formation, and neurite outgrowth
Neurite formation is a fundamental antecedent to axon and dendrite formation, but the mechanisms that underlie this important process are poorly characterized. Here, we demonstrate that two F-BAR proteins, CIP4 and FBP17, have opposing functions in early cortical neuron development.
- ATP hydrolysis by KaiC promotes its KaiA binding in the cyanobacterial circadian clock system
ATP hydrolysis in the KaiC hexamer triggers the exposure of its C-terminal segments into the solvent so as to capture KaiA, providing mechanistic insights into the circadian periodicity regulation.
- The S. Typhi effector StoD is an E3/E4 ubiquitin ligase which binds K48- and K63-linked diubiquitin
Salmonella Typhi is estimated to cause 100,000–200,000 deaths annually, yet its infection strategy remains elusive. This article reports of the first Typhi-specific effector, which has an E3/E4 ubiquitin ligase activity and can uniquely bind K48- and K63-linked diubiquitin.
- PKAc is not required for the preerythrocytic stages of Plasmodium berghei
The mutant salivary gland sporozoites lacking PKAc are able to glide, invade hepatocytes, and mature into hepatic merozoites, which release successfully from the merosome, however, fail to initiate blood stage infection when inoculated into mice.
- The m6A pathway protects the transcriptome integrity by restricting RNA chimera formation in plants
This study reveals that an m6A-assisted polyadenylation pathway comprising conserved m6A writer proteins and a plant-specific m6A reader contributes to transcriptome integrity in Arabidopsis thaliana by restricting RNA chimera formation at rearranged loci.
- Tumor-intrinsic response to IFNγ shapes the tumor microenvironment and anti–PD-1 response in NSCLC
Using an immunocompetent mouse model of NSCLC, this study demonstrates that tumor-intrinsic response to IFNγ determines response to anti–PD-1 through alterations in the tumor microenvironment.
- Molecular characterization of CHAD domains as inorganic polyphosphate-binding modules
A domain of unknown function termed CHAD, present in all kingdoms of life, is characterized as a specific inorganic polyphosphate-binding domain.
- Rate of brain aging and APOE ε4 are synergistic risk factors for Alzheimer’s disease
This study describes a gauge for brain aging predictive of cognitive decline and Alzheimer's disease synergistic with the APOE ε4 allele.
