Calcium induced N-terminal gating and pore collapse in connexin-46/50 gap junctions
Abstract Gap junctions facilitate electrical and metabolic coupling essential for tissue function. Under ischemic conditions (e.g., heart attack or stroke), elevated intracellular calcium (Ca2+) levels uncouple these cell-to-cell communication pathways to protect healthy cells from cytotoxic signals. Using single-particle cryo-EM, we elucidate details of the Ca2+-induced gating mechanism of native connexin-46/50 (Cx46/50) gap junctions.

Connexin-46/50 in a dynamic lipid environment resolved by CryoEM at 1.9 Å
Abstract Gap junctions establish direct pathways for cells to transfer metabolic and electrical messages. The local lipid environment is known to affect the structure, stability and intercellular channel activity of gap junctions; however, the molecular basis for these effects remains unknown. Here, we incorporate native connexin-46/50 (Cx46/50) intercellular channels into a dual lipid nanodisc system, mimicking a native cell-to-cell junction.
Gas-Phase Optical Detection of 3-Ethynylcyclopentenyl: A Resonance-Stabilized C7H7 Radical with an Embedded 1-Vinylpropargyl Chromophore
The 3-ethynylcyclopentenyl radical (3ecpr) has been identified as the carrier of an electronic spectrum with origin at 21792 cm–1 using resonant ionization and laser-induced fluorescence spectroscopies. The radical was first detected in a toluene discharge and is most efficiently produced from 1,6-heptadiyne.
