Human FASTK preferentially binds single‐stranded and G‐rich RNA
The FEBS Journal, Volume 293, Issue 3, Page 729-748, February 2026.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 ...

Transglutaminase‐mediated cytokeratin modifications implicated in bile‐acid‐induced hepatocyte death
The FEBS Journal, Volume 293, Issue 4, Page 1089-1105, February 2026.Cholestasis and bile‐acid exposure enhance expression and activity of protein crosslinking enzymes TG1 and TG2 in hepatocytes. Substrate proteins were identified by mass spectrometry using biotin‐labeled peptides (pepK5/pepT26) or amine donor (biotinylated pentylamine; BPA). Crosslinking‐induced aggregation and fragmentation of keratin 18 and 8 (K18/K8)

The FEBS Journal, Volume 293, Issue 4, Page 1127-1149, February 2026.Advanced techniques to visualize the spatiotemporal functionality of biomolecules are essential for elucidating mechanisms governing cellular behavior. External apodization phase‐contrast (ExAPC) microscopy enables label‐free visualization of diverse intracellular structures in living mammalian cells. By enhancing phase‐contrast imaging through optical

Sensing of cardiolipin exposure on plasma membranes of apoptotic cells by EryA‐mCherry protein
The FEBS Journal, Volume 293, Issue 4, Page 1150-1167, February 2026.An aegerolysin protein erylysin A (EryA) fused with mCherry binds to artificial lipid vesicles supplemented with cardiolipin (CL). This binding is much more specific than that of annexin V, which binds various negatively charged glycerophospholipids (PG, PS, PI). In mammalian cells, the CL exposition at the membrane surface represents an early hallmark
