Human FASTK preferentially binds single‐stranded and G‐rich RNA

The FEBS Journal, EarlyView.
Although FASTK is known to play a role in mRNA biology, the mechanism through which it recognizes RNA has yet to be unraveled. Here, we used purified human FASTK to characterize its RNA‐binding properties in vitro. We found that FASTK prefers ssRNA oligonucleotides containing guanines with the potential to form G‐quadruplexes and binds robustly to any ...

Vaspin identified as a DNA‐binding serpin with functional consequences for protease inhibition

The FEBS Journal, EarlyView.
Vaspin is a serpin that is expressed in skin, adipose tissue, and liver. It binds to single‐ and double‐stranded DNA with high affinity. This binding is unaffected by mutation of the known heparin‐binding site, accelerates the inhibition of the inflammatory protease KLK7, and may contribute to vaspin's nuclear localization.

The ribosome‐associated complex regulates cytosolic translation upon mitoprotein‐induced stress

The FEBS Journal, EarlyView.
Defects in mitochondrial protein import trigger a stress response. The contribution of translation regulation to such a response is only partially understood. We demonstrate that the deletion of mitochondrial surface proteins (TOM70/TOM71) leads to defects in mitochondrial biogenesis and slow growth.

Coenzyme A mitigates cystine‐deprivation‐induced ferroptosis by suppressing the iron‐starvation response

The FEBS Journal, EarlyView.
Cystine (Cys2) deprivation in pancreatic cancer cells induces oxidative stress that destabilizes cytosolic iron–sulfur cluster (ISC) proteins, triggering an iron‐regulatory protein (IRP)‐mediated iron‐starvation response (ISR). This leads to increased iron uptake (via TFRC), an expanded labile iron pool, and ferroptosis.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, EarlyView.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

KRP3 Stability Controls Rice Plant Architecture and Productivity via MPK3‐Mediated Phosphorylation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Yield is a critical agronomic trait in cereal crops, shaped by factors like tiller and seed number, and seed weight. Understanding the factors governing these traits will help in improving the yield of plants. In this study, we identified an orphan gene, KRP3, belonging to cereal crops as a key regulator of rice plant architecture.

Subclass III SnRK2 Kinases Coordinate Starch and Storage Protein Synthesis During Maize Kernel Development

Plant Biotechnology Journal, EarlyView.
ABSTRACT Enhancing both starch and protein accumulation is a key strategy for improving maize yield and quality. Achieving this goal requires an in‐depth understanding of the regulatory mechanisms that integrate these pathways. Here, we demonstrate that functionally redundant subclass III SNF1‐related protein kinase 2s (SnRK2s) act as central ...

Jasmonate Modulates Strawberry Susceptibility to Anthracnose by Activating SnRK2.1 to Regulate the WRKY50‐JAZ5 Module

Plant Biotechnology Journal, EarlyView.
ABSTRACT Colletotrichum spp., hemibiotrophic fungal pathogens, threaten global strawberry production. Jasmonate (JA) regulates plant‐Colletotrichum interactions, but its mechanisms remain unclear. Here we demonstrate that both exogenous methyl jasmonate (MeJA) treatment and elevated endogenous MeJA levels increase strawberry susceptibility to ...

Rapid synthesis and turnover of brain microsomal ether phospholipids in the adult rat

Journal of Lipid Research, 2002
The rates of synthesis, turnover, and half-lives were determined for brain microsomal ether phospholipids in the awake adult unanesthetized rat. A multicompartmental kinetic model of phospholipid metabolism, based on known pathways of synthesis, was ...

The IQ‐compete assay for measuring mitochondrial protein import efficiencies in living yeast cells

FEBS Letters, Volume 600, Issue 1, Page 48-62, January 2026.
The efficiency of mitochondrial protein import depends on the properties of the newly synthesized precursor proteins. The Import and de‐Quenching Competition (IQ‐compete) assay is a novel method to monitor the import efficiency of different proteins by fluorescence in living yeast cells.
