A structure of a pancreatic ATP-sensitive potassium channel complex at 3.63Å resolution obtained by cryo-electron microscopy reveals how a commonly used anti-diabetic drug interacts with and inhibits the channel to stimulate insulin secretion.

Cryo-EM structures of the 30S*RNAP complex visualize co-localization of the transcription and translation machineries and provide insights into the transcription-translation synchrony, which coordinates gene expression in bacteria.

The molecular chaperone BIP from the endoplasmic reticulum is fine-tuned postranslationally through the thermodynamic and kinetic alterations in its conformational ensemble of functionally and structurally distinct physiological forms.

A multidisciplinary platform featured by patient-derived RPEs is established to study the disease-causing mechanisms of BEST1 mutations, and demonstrates gene-supplemented rescue of the mutation-caused deficiency in Ca²⁺-dependent Cl^- current in human RPE.

Generation of a highly deuterated 13C-methyl labeled wild-type GPCR sample is used to facilitate characterization of the molecular environments and fast ps-ns dynamics of sidechains when the receptor is bound to ligands of different efficacy.

The DNA-bridging efficiency of H-NS, a genome organising and transcription regulatory protein, is modulated by changes in environmental conditions of the cell, which drive a structural rearrangement of the protein.

Cryo-electron microscopy and genetics show how Staphylococcus aureus pathogenicity island 1 hijacks the assembly pathway of a helper phage for its own propagation.

The Ras activator RasGRP1 that impacts Ras signals in immune cells, leukemias, and colorectal cancer, switches to an active conformation aided by a pH-sensitive histidine residue in a central location of the RasGRP1 molecule.

The ion-transport pathway of an unconventional bacterial fluoride channel is mapped out through combined crystallographic and functional experiments.

A concerted approach employing equilibrium and biased molecular simulations, electrophysiology, mutagenesis, and functional assays reveals, in atomic details, the mechanism and pathway for transport of phospholipids and ions by a lipid scramblase.
