Two novel LOTUS-domain proteins are core germ granule components that directly recruit Caenorhabditis elegans Vasa, regulate germ granule size and localization, and provide an organizational framework for ribonucleoprotein complexes.
By driving the localized contraction of subcellular muscle regions, a single motor neuron reverses the flow of material in the Caenorhabditis elegans pharynx, a neuromuscular pump, converting feeding into spitting.
The most common Parkinson’s disease-associated mutation, LRRK2 G2019S, impairs mitophagy in clinically relevant cells within the mouse brain and this defect can be reversed using a novel LRRK2 inhibitor.
Transgenic mice and cell models provide evidence of a pathophysiological mechanism that connects mtDNA damage to cardiac dysfunction via reduced NAD+ levels and loss of mitochondrial function and communication.
The extension of covariation analyses to proteins that coevolve but do not physically interact enabled identification of selectivity residues in quorum sensing proteins, providing insight into the evolution of signaling systems.
The C-terminus of A2A receptor drives oligomer formation via an intricate network of disulfide bonds, hydrogen bonds, electrostatic interactions, and hydrophobic interactions, all of which are enhanced by depletion interactions.
Exposure to Bacillus thuringiensis (Bt) selects for beneficial interactions between the target insect pest (Helicoverpa armigera) and its symbiotic densovirus that enhances its performance on Bt-crops under field conditions.
