Heat shock protein drives yeast evolution

Whitehead Institute researchers have determined that heat shock protein 90 (Hsp90) can create heritable traits in brewer's yeast (Saccharomyces cerevisiae) by affecting a large portion of the yeast genome. The finding has ...

Study demonstrates 'tunability' of a molecular chaperone

For decades, molecular biologists studying a class of molecular chaperones known as heat shock proteins (Hsp70s) have relied on the Hsp70s found in bacteria as the model system. Now one of the world's experts on the molecule ...

Scientists discover new function of heat-shock protein

An international research team has identified a new function of Hsp90, one of the most common and studied proteins in the human body. The study has implications for the development of new drugs.

Infrared sensor as new method for drug discovery

Using an infrared sensor, biophysicists at Ruhr-Universit├Ąt Bochum (RUB) have succeeded in analysing quickly and easily which active agents affect the structure of proteins and how long that effect lasts. Thus, Prof Dr. ...

Plants feel the heat

It's not just humans and animals that suffer when the mercury rises, plants feel the heat too. Heat stress is a major issue in agriculture and can significantly reduce crop yield. Even small increases in temperature can affect ...

Researchers discover new pathway for handling stress

Balance is key to many physiological functions and it is especially true in the production and regulation of proteins. A balance of proteins in cells helps maintain health, but an unhealthy clumping can lead to a variety ...

Microscopic collisions help proteins stay healthy

Studies at The University of Texas Health Science Center at San Antonio are providing basic new understanding about "heat shock proteins," also called "chaperone proteins." These proteins, first identified in cells subjected ...

Cell stress response and fat and obesity gene linked

In one fell swoop, Cornell researchers have discovered mechanisms that control the function of a fat and obesity gene while at the same time answering a long-standing question about how cells respond to stress.
