Researchers have developed an electroporation-based NMR method that delivers labeled proteins into intact mitochondria, ...

A protein that's essential to every cell's ability to turn off unnecessary genes is well known for its key function of ...

Leucine, the amino acid sold in tubs and bars for building muscle, also stands guard over the machinery inside mitochondria.

To sense their environment and respond accordingly, cells enlist membrane proteins as communication hubs, receiving molecular messages from outside and triggering responses inside. One of these ...

Once a receptor protein receives a signal, it undergoes a conformational change, which in turn launches a series of ...

Scientists at Scripps Research have engineered a synthetic protein capable of binding to Toll-like receptor 4 within the cell ...

Human liver cells showing collagen droplets inside the cell (green clusters), held in place by TANGO1 (magenta), with extracellular collagen fibres visible as the surrounding network. Cell nuclei are ...

In new research, scientists at the Department of Energy's SLAC National Accelerator Laboratory, in collaboration with researchers at Harvard University and Brigham Young University, used the ...

How cells sense fluctuations in the availability of water has long been unclear. The protein SAM8 is now shown to undergo a process called phase separation in a way that depends on its hydration, ...

Scientists in China have uncovered a molecular trick that colon cancer cells use to survive what should be an explosive death ...

New UC Riverside-led research suggests Alzheimer’s arises not simply from plaques forming in the brain, as is widely believed, but from one protein interfering with the normal job of another. For ...

Scientists from Memorial Sloan Kettering have collaborated on the discovery of a unique monoclonal antibody, called ESK1, that appears to be effective at targeting and destroying several types of ...
