The formation of neuronal networks relies on the proper development and targeting of the neurons within. The actin cytoskeleton plays an important role during the process of axon guidance. The non-catalytic subunit of the Drosophila NatB complex, Psidin, is essential to maintain the actin cytoskeleton in a dynamic and responsive state. At the same time Psidin, together with the catalytic part of the NatB complex, is required for the survival of neurons.

A newly identified hearing organ in a South American bush cricket, which possesses one of the smallest ears known, shows insect hearing is so sophisticated that it rivals our own. The study, published in Science, is the first to identify a hearing mechanism in an insect that is evolutionarily convergent to those of mammals.

There are many examples of peptides that self-assemble to form long, fibrous structures. Forming closed assemblies is more difficult. This HFSP-funded study shows that two α-helical peptides can be joined by a series of peptide linkers of different lengths to form a range of new peptide assemblies. The structure formed depends on the length of the linker employed, with short linkers favoring fibers and the longer linkers leading to closed nanostructures.

Viruses are masters of using cells for their own purposes. We have synthetically recreated how HIV attracts so called ESCRT proteins - normally involved in cell division - to the sites where new virus particles are released from an infected cell.

In eukaryotic cells, co-translational protein translocation across the endoplasmic reticulum (ER) membrane requires an elaborate macromolecular machinery comprising the 80S ribosome and the translocon complex. Here, we used cryoelectron tomography and subtomogram averaging to provide a three-dimensional reconstruction of ER membrane associated 80S ribosomes and a description of their spatial organization in situ.

Photo damage and inappropriate mounting strategies limit the duration of in vivo imaging in conventional microscopy techniques. Combining light sheet microscopy with optimized mounting methods allows physiological imaging over days.

In eukaryotes, calmodulin-stimulated calcium pumps including plasma-membrane Ca2+-ATPases are key regulators in intracellular Ca2+ concentration. The precise mechanism of how these pumps are regulated remained elusive. Here, we identified a bimodular, calmodulin-mediated activation mechanism of plasma-membrane Ca2+-ATPases.

The assembly-disassembly dynamics of cytoskeletal polymers such as actin filaments and microtubules support motile and morphogenetic processes in eukaryotes. Understanding the detailed molecular mechanisms by which these dynamic processes are controlled is a challenging task that requires combined biochemical and biophysical approaches. New technological developments in monitoring single actin filament dynamics with unprecedented accuracy and temporal resolution allows quantitative theoretical analysis...

A comparative genomics approach predicts which genomic regions are linked to natural phenotypic differences between species, leveraging specificity resulting from independent phenotypic losses.

Cell confinement, by controlling cell spreading, defines the behavior of epithelial cells in the tissues. Low cell confinement limits peripheral actin contractility and promotes centrosome positioning and lumen initiation. This peripheral actin contractility depends on the RhoA–ROCK–myosin II pathway, which is downstream of master kinase Par-4/LKB1.
