The regulatory switch from protection to assimilation, which plants use to exploit natural, fluctuating light, involves movement of the enzyme ferredoxin:NADP(H) oxidoreductase between chloroplast membrane complexes.
The combined use of NAD+ with ribitol or ribose potentiates the rescue of α-dystroglycan functional glycosylation in FKRP-mutant patient-specific iPSC-derived myotubes, representing potential novel treatments for FKRP muscular dystrophies.
Serial-Block-Face Scanning Electron Microscopy (SBF-SEM) associated with biomolecular analysis show that chloroplast differentiation proceeds by distinct ‘structure establishment’ and ‘chloroplast proliferation’ phases, each with differential protein and lipid regulation.
When neurons are stimulated, calcium entry into mitochondria upregulates mitochondrial energy production, but glycolytic energy production in the cytosol is stimulated by elevated energy demand, not Ca2+ signaling.
A widespread family of chaperones functions to stabilize membrane protein effectors by mimicking transmembrane helical environments and promotes effector export by the bacterial type VI secretion system.
