• How Kinase Inhibitors Tune p38α Dephosphorylation

  2026-09-21

  This bioRxiv study identifies a dual-action mode in which selected kinase inhibitors both block p38α catalytic activity and increase its dephosphorylation by the phosphatase WIP1. Biochemical experiments and X-ray structures link this effect to an inhibitor-stabilized activation-loop conformation, offering a framework for designing kinase inhibitors that promote target-specific phosphatase action.

• 4-MUG: A Translational Lens on GCase

  2026-09-21

  4-Methylumbelliferyl-β-D-Glucopyranoside converts β-glucocerebrosidase activity into a sensitive fluorescent readout that can help translational teams evaluate GBA1 mRNA designs, lysosomal rescue, and assay robustness.

• Why SOD Matters in NADPH-Linked Amplex Red Assays

  2026-09-20

  Mishina and colleagues show that NADPH or NADH can generate superoxide through interactions with horseradish peroxidase, producing peroxide-related background that compromises continuous Amplex Red measurements. Adding superoxide dismutase suppresses this interference without measurably reducing microsomal hydrogen peroxide formation, enabling more reliable rate measurements in NAD(P)H-supported enzyme assays.
