Protein aggregates that form after a cell is exposed to high, non-lethal temperatures appear to be part of an organized response to stress, and not the accumulation of damaged proteins en route to destruction. Reporting in ...

Similar to a hybrid car that switches from gas to electric as it drives on major highways and secondary roads, Cornell researchers have discovered that the cell's protein-making machinery, called ribosomes, exists in a hybrid ...

Living cells are like miniature factories, responsible for the production of more than 25,000 different proteins with very specific 3-D shapes. And just as an overwhelmed assembly line can begin making mistakes, a stressed ...

(Phys.org) —A team of researchers with members from several facilities in California and from one in Australia has found evidence that an unfolded-protein-response can both activate and degrade the death receptor 5 protein ...
When an organism is exposed to life-threatening conditions, it sounds the alarm and a cellular emergency program, the heat shock response, is initiated. However, the name "heat shock response" is misleading. In the beginning ...
