The use of genetically encoded redox sensors in phagocytized bacteria reveals that, among the toxic cocktail of oxidants released into the neutrophil's phagolysosome, HOCl is the main component responsible for the oxidative modification of bacterial protein thiols.

The chloroplast 2-cysteine peroxiredoxin is central player and missing link in the chloroplast thiol-disulfide redox regulatory network, and participates in oxidative inactivation of reductively activated enzymes in photosynthesis.

High variability in neuropathology burden and interactions between dementia diagnosis and RNA quality present underappreciated complications when studying dementia in an aged population.

Key sequence motifs, defined using the first reported structure of a monotopic membrane protein with a reentrant helix, enable identification of new monotopic membrane protein families previously predicted as membrane spanning.

Ligand binding, force and chemistry combine to control the function of a cell surface receptor.

Secretion of the inflammatory cytokine TNF requires a protein called iTAP/FrmD8, which controls the cell surface stability of the TNF shedding machinery, iRhom2 and TACE/ADAM17.

An in vivo disulfide crosslinking assay shows preferential disassembly of nucleosomes with two H2A.Z histones by transcription machinery in yeast and conjugation to one or two ubiquitin moieties in human cells.

C. elegans utilizes bacterially produced nitric oxide as a sensory cue to elicit avoidance of pathogenic bacteria.

In the plant circadian clock photoreceptor ZEITLUPE, evolutionarily selected residues distinguish photocycle kinetics and allosteric signal transduction pathways to permit proper circadian timing.
