The notion that the lumen of the ATP synthase membrane rotor is the long-sought megachannel that triggers the onset of the mitochondrial permeability transition is found to be inconsistent with its actual structural and functional properties.
Polymorphic residues of a vacuolar Ca2+ sensor site in TPC1 channels differ between species of Brassicacea and Fabaceae and lead to distinct TPC1 gating behavior.
Loss of the F-ATP synthase c-subunit inhibits a pathological mitochondrial permeability transition pore that is coupled to a maladaptive mitochondrial unfolded protein response while also extending lifespan.
Contrary to a generally accepted principle, the pore properties of KCNQ1 channels depend on the states of voltage-sensing domains activation; KCNE1 alters the voltage-sensing domains-pore coupling to modulate KCNQ1 channel properties.

The molecular mechanism that candidalysin uses to perforate membranes is unraveled, which opens the door to the rational design of inhibitors against candidiasis.

Cryo-EM structures of Cys-loop receptor Alpo4 from the thermophilic worm Alvinella pompejana show that a sterol derivative CHAPS binds in and outside of its orthosteric binding site and induces a quaternary twist.

Electron and atomic force microscopy show how bacterial toxins bind to a host membrane and assemble into arcs and rings, before undergoing a dramatic, concerted conformational change to insert into the membrane.
T-cell receptor signaling actively regulates gating of the nuclear pore complex (NPC) in T cells by inducing translocation of protein kinase C-θ to the NPC to promote the sumoylation of RanGAP1.
The conformation of an isoleucine gate located along the TM6 segment on the intracellular side below the selectivity filter is a critical component leading to a non-conductive state in the C-type inactivation process of K+ channels.
