FEBS Letters, EarlyView.This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Proyecciones (Antofagasta)We give a characterization in terms of the transpose operator for a continuous linear operator between locally convex spaces to map bounded sets into relatively weakly compact [relatively compact, precompact] sets. Our results give a known characterization for compact operators between Banach spaces.

In situ molecular organization and heterogeneity of the Legionella Dot/Icm T4SS
FEBS Letters, EarlyView.We present a nearly complete in situ model of the Legionella Dot/Icm type IV secretion system, revealing its central secretion channel and identifying new components. Using cryo‐electron tomography with AI‐based modeling, our work highlights the structure, variability, and mechanism of this complex nanomachine, advancing understanding of bacterial ...

Compactness and local compactness in hyperspaces
Topology and its Applications, 2002 In their interesting paper the authors treat compactness and relative compactness of subsets of hyperspaces, where the hyperspaces are considered to be equipped with the Vietoris, the Wijsman and partly the Hausdorff metric topology. Included in the paper are also characterizations of local compactness with respect to the mentioned hyperspace ...

Sequence determinants of RNA G‐quadruplex unfolding by Arg‐rich regions
FEBS Letters, EarlyView.We show that Arg‐rich peptides selectively unfold RNA G‐quadruplexes, but not RNA stem‐loops or DNA/RNA duplexes. This length‐dependent activity is inhibited by acidic residues and is conserved among SR and SR‐related proteins (SRSF1, SRSF3, SRSF9, U1‐70K, and U2AF1).

, 2018 The compact-table propagator for table constraints appears to be a strong candidate for inclusion into any constraint solver due to its efficiency and simplicity. However, successful integration into a constraint solver based on copying rather than trailing is not obvious: while the underlying bit-set data structure is sparse for efficiency it is not ...

On Countable Compactness and Sequential Compactness [PDF]
Proceedings of the American Mathematical Society, 1984 If a countably compact T 3 {T_3} space X X can be expressed as a union of less then c c many first countable subspaces, then MA implies that X X is sequentially compact.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
