KR-12–Cu(II) Binding: A Multiscale Study
2026-08-13
The reference study integrates GFN2-xTB/ALPB quantum calculations with potentiometric titration and isothermal titration calorimetry to resolve how KR-12 peptides coordinate Cu(II). Its main contribution is showing that backbone oxygen atoms dominate favorable binding modes while selected acidic and arginine residues shape the interaction landscape, illustrating why computation is valuable for interpreting dynamic peptide–metal systems.

CD28–ARS2 Splicing Builds CD8+ T-Cell Flexibility
2026-08-07
Holling and colleagues identify a CD28–ARS2 signaling axis that reshapes PKM alternative splicing in activated CD8+ T cells, favoring PKM2 over PKM1 and supporting flexible glucose use, interferon-γ production, and antitumor activity. The study separates this post-transcriptional metabolic control from canonical CD28–PI3K signaling and provides a framework for connecting costimulation, RNA processing, and T-cell function.
