Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.

Linking the DNA repair template to the Cas9 ribonucleoprotein complex enhances homology-directed repair of the induced DNA double strand break.

Cryo electron microscopy and structure-based mutagenesis reveal that the bacteriophage BPP-1 contains two of the three major recognized viral folds, one of which exhibits a new topology.

The same genes and signaling pathways control the formation of limbs in vertebrates, arthropods and cuttlefish.

Coarse-grained modeling reveals a new mechanism for multispanning membrane protein topogenesis, in which misintegrated configurations of the proteins undergo post-translational annealing to reach final, fully integrated multispanning topologies.

Key sequence motifs, defined using the first reported structure of a monotopic membrane protein with a reentrant helix, enable identification of new monotopic membrane protein families previously predicted as membrane spanning.

Oscillatory synchronized hub neurons coordinate neural network activity across multiple brain areas.

Tissue-specific temporal regulators impinge on the VEGF/Delta-Notch pathway to vary tip cell selection pace yielding diverse densities of vascular network.

The high-resolution structure of a filamentous flexible plant virus shows that there is structural homology between its coat protein and the nucleoproteins of an unrelated group of enveloped RNA animal viruses.

Building on previous work (Jinek et al., 2013), we report a simple and robust system to achieve high fidelity and high efficiency (30% of homologous recombination) genome engineering by homology-directed repair pathway in human cells using cell cycle synchronization and timed delivery of Cas9 ribonucleoprotein complexes.
