Aconitate decarboxylase 1-derived itaconate reduces mitochondrial respiration via inhibition of succinate dehydrogenase but does not regulate inflammatory response or NRF2 expression in response to particulate matter.
Modulation of the energy barrier for membrane fusion is a common mechanism by which sensors in the synapse produce supralinear calcium dependence of vesicle release and short-term synaptic potentiation.
Neuroligin 1 is a critical adhesion molecule which organizes AMPA receptor nanodomains in close vicinity to pre-synaptic release sites, and whose genetic or chemical disruption severely impairs synaptic transmission properties.
Heat shock induces relocalization of epigenetic modifiers to the nucleolus, which acts as a dedicated protein quality control center that is indispensable for recovery of epigenetic regulators and epigenetic modifications.
Cryo-electron microscopy has been used to provide a structural interpretation of the complete action cycle of release factor 3 during translation termination, which includes a coordinated sequence of interactions with a class-I release factor and the ribosome.
The conformational dynamics of multidrug resistance protein 1 (MRP1) are tracked in real time by single-molecule fluorescence resonance energy transfer experiments, which elucidate the rate-limiting mechanism of MRP1's transport cycle.
