Multifaceted properties of the water-soluble derivative of antibiotic heliomycin enable it to offer greater antitumor value than its parent compound by inhibiting the tNOX-NAD+-SIRT1 axis to induce apoptosis.
New ATP-competitive inhibitors show properties of conformation selection when complexed with the MAP kinase, ERK2, altering movements around the activation loop.

Thioredoxin functions as a negative allosteric effector of ASK1 by altering the interaction between the thioredoxin-binding and tetratricopeptide repeats domains, thereby reducing access to the kinase domain's activation segment.
Blinding the initial review of applications for Beckman Young Investigator awards reduces prestige bias, but has no impact on the success rates for different genders.
The intrinsic disorder of the circadian clock protein Frequency organizes binding partners, facilitates liquid–liquid phase separation, modulates Frequency phosphorylation, and derives from sequence properties conserved with homologous clock components.
