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

open access: yesThe 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 ...

Overcoming BET‐inhibitor JQ1 resistance in aggressive non‐small cell lung cancer by inducing ferroptosis via inhibition of the BRD2–FTH1 axis

open access: yesThe FEBS Journal, EarlyView.
Recent studies emphasize alternative functions of FTH1 relevant for nuclear processes, such as transcriptional regulation. This study shows a novel FTH1/BRD2 association in non‐small cell lung carcinoma (NSCLC). This nuclear interaction affects BRD2 protein stability in aggressive NSCLC cells.

Mechanism of cyanobacterial ferredoxin‐dependent flavin thioredoxin reductase reveals thiolate‐FAD charge transfer and catalytic asymmetry in a homodimer

open access: yesThe FEBS Journal, EarlyView.
Ferredoxin‐dependent flavin thioredoxin reductases (FFTRs) regenerate reduced thioredoxin, sustaining dithiol–disulfide exchange reactions that regulate protein activity in select organisms. In cyanobacterial FFTRs, we describe the formation of a thiolate–flavin charge transfer complex, asynchronous reduction of the two FAD cofactors within the ...

Evolutionary divergence and functional insights into the heteromeric cis‐prenyltransferase of Paramecium tetraurelia

open access: yesThe FEBS Journal, EarlyView.
Heteromeric cis‐prenyltransferases (CPT) are indispensable for dolichol synthesis and protein N‐glycosylation in most eukaryotes. The catalytic subunits are strongly conserved throughout evolution, in contrast to the evolutionarily variable accessory subunits. The POC1 protein from Paramecium tetraurelia is the smallest identified CPT‐accessory subunit

TGFβ enhances platelet–breast‐cancer‐cell interaction and promotes platelet aggregation

open access: yesThe FEBS Journal, EarlyView.
TGFβ stimulation promotes EMT in MCF7 cells, increasing their ability to bind, activate, and aggregate PLT. This effect involves the upregulation of adhesion molecules Integrin‐αv and Galectin‐3. Inhibiting Integrin‐αv or Galectin‐3, through Cilengitide and GB1103, reduces PLT adhesion to MCF7 and PLT aggregation, suggesting a mechanism linking TGFβ ...

Leishmania donovani's protein tyrosine phosphatases interact with DUF21 and respond to environmental magnesium

open access: yesThe FEBS Journal, EarlyView.
The Leishmania phosphatase PTP1, and possibly the genetically similar PTP2, interacts with the Leishmania transmembrane protein DUF21. When both ptp1 and ptp2 are knocked out of Leishmania (LdΔPTP1/2), the parasite can no longer survive without magnesium in vitro and has reduced viability in the host macrophage. Conversely, in duf21 knockout (LdΔDUF21),
