MIT researchers have designed a new type of probe that can image thousands of interactions between proteins inside a living cell, giving them a tool to untangle the web of signaling pathways that control most of a cell's activities.

A team of Canadian researchers has completed a massive survey of the network of protein complexes that orchestrate the fundamental processes of life.

In the late 19th century the Czech scientist Franz Hofmeister observed that some salts (ionic compounds) aided the solution of proteins in egg white, some caused the proteins to destabilize and precipitate, and others ranged in activity between these poles.

Carnegie Mellon University’s Justin Y. Newberg and Robert F. Murphy have developed a software toolbox that is intended to help bioscience researchers characterize protein patterns in human tissues.

More than 600 million years of evolution has taken two unlikely distant cousins – turkeys and scallops - down very different physical paths from a common ancestor. But University of Leeds researchers have found that a motor protein, myosin 2, remains structurally identical in both creatures.

A new study shows how genes control levels of many blood proteins implicated in disease. The findings are the result of an international collaboration between scientists at the University of Exeter, the National Institute on Aging, and the Tuscany and Florence Health Agencies.

Researchers in Korea report development of a way to double production of a sticky protein from marine mussels destined for use as an antibacterial coating to prevent life-threatening infections in medical implants. The coating, produced by genetically-engineered bacteria, could cut medical costs and improve implant safety, the researchers say.

Dutch chemist Paul Poodt has developed two attractive alternatives for allowing protein crystals to grow under weightless conditions. If the crystals are grown upside down in a strong magnetic field, fluid flows that disrupt crystal growth are suppressed. Therefore, high-quality proteins no longer need to be grown in space, but can be grown here on earth.

Researchers from the Virginia Bioinformatics Institute (VBI) at Virginia Tech and their colleagues have identified a key function of a large family of virulence proteins that play an important role in the production of infectious disease by the plant pathogen Phytophthora sojae.

New findings about a protein called the nogo receptor are offering fresh ways to think about keeping the brain sharp.

The thousands of proteins found in nature are simply strings of amino acids, assembled by genes, and scientists have long believed that they automatically fold themselves into uniquely fixed, 3-dimensional shapes to fire the engine of life. In the era of genetic research, identifying those shapes and their functions has become a worldwide focus of biomedical science.

Using a systems biological analysis of genome-scale data from the model plant Arabidopsis, an international team of researchers identified that the master gene controlling the biological clock is sensitive to nutrient status.
