Aurora A kinase is a key regulator of cell division, whose functions were attributed to its ability to phosphorylate diverse substrates. Aurora A is now shown to have a kinase-independent role in the regulation of chromatin-mediated microtubule assembly.

As a microtubule-organizing center, the centrosome undergoes a dramatic increase in size - via expansion of the pericentriolar material - during mitosis. Recent work reveals shared assembly properties of a protein scaffold that facilitates and supports this expansion, a process critical to spindle assembly.

Li et al. demonstrate that a single interneuron can regulate analog- and digital-like behaviors guided by two different postsynaptic neurons. Releasing a single neurotransmitter onto downstream neurons that express receptors with distinct biophysical properties enables a small set of neurons to direct a range of functional responses.

Screening a library of expressed cyclic peptides identified clones that reverse the cytotoxicity of alpha-synuclein in yeast and Caenorhabditis elegans. The results suggest a new approach for intervention in Parkinson's disease, and perhaps a druggable target.

In the defecation motor program of Caenorhabditis elegans, a pacemaker rhythm generated by the intestine leads to the activation of motor neurons controlling enteric muscle contraction. A new study demonstrates that this signal is conveyed by a neuropeptide that is released from intestinal cells and acutely depolarizes the motorneurons, acting much like a classical neurotransmitter.

Using Caenorhabditis elegans as a model system, Norris et al. (2014) define complex combinatorial regulation of alternative splicing at single-neuron resolution and illustrate functional coherence among components of a splicing regulatory network controlled by a neuronal splicing factor.

A recent study identifies a role for a Toll pathway with likely non-canonical features in the developmental specification of BAG neurons in Caenorhabditis elegans. These neurons function to sense carbon dioxide, which is shown to facilitate avoidance of pathogenic bacteria.
