How to kill a protein

For decades scientists have been looking closely at how our cells make proteins. But the inverse is equally important: how cells kill them.

Immunoproteasome crystal structure determined

Like a shredder, the immunoproteasome cuts down proteins into peptides that are subsequently presented on the cellular surface. The immune system can distinguish between self and nonself peptides and selectively kills cells ...

Watching the cogwheels of the biological clock in living cells

Our master circadian clock resides in a small group of about 10'000 neurons in the brain, called the suprachiasmatic nucleus. However, similar clocks are ticking in nearly all cells of the body, as demonstrated by the group ...

Scientists discover new way protein degradation is regulated

(Phys.org) —Proteins, unlike diamonds, aren't forever. And when they wear out, they need to be degraded in the cell back into amino acids, where they will be recycled into new proteins. Researchers at Rockefeller University ...

Research shows how cells handle big trash pickup

Everyone would rather cook than take out the garbage. Perhaps that's why biochemists learned how cells make proteins 70 years ago, but are just now learning how they get rid of proteins that are no longer needed or no longer ...
