The structure of the photosystem I (PSI) complex from Synechocystis is determined, and reaction center subunits engineered to resemble a viral PSI are found to promote promiscuous electron acceptor properties.
Optogenetic techniques, whereby light is used to activate neuronal cells, are quickly becoming widely used in neuroscience; but excessive exposure to light can actually silence certain types of neuronal cells.
New insights into the assembly and membrane interactions of the caveolar coat complex reveal the reversible association/dissociation of distinct subcomplexes onto the membrane, which differs from the assembly/disassembly of clathrin-coated pits.
Systems-level analysis in vertebrate ciliated epithelial cells shows that the network of genes activated by the transcription factor Rfx2 controls the development, migration, insertion and function of these cells.
A deubiquitinase antagonizes the activity of an associated E3 ligase to prevent uncontrolled ubiquitination of a degradation machinery protein and thus maintain its functionality in protein quality control at the endoplasmic reticulum.
