Proteins that are no longer needed, defective, or potentially harmful are labeled with a molecular "tag" and dismantled in ...

Two proteins found on the surface of motor neurons in the brain may be essential in the progression of Parkinson's disease, ...

A Northwestern Medicine study has revealed a previously unknown connection between two fundamental cellular processes, ...

The average human cell contains roughly 10,000 different proteins. Existing as several to millions of copies in each cell, proteins mediate all manner of tasks, including chemical transformations, ...

Researchers at the Indian Institute of Science (IISc), with collaborators from the Institute of Mathematical Sciences (IMSc), ...

Recent research has identified a specific biological mechanism that may explain why females experience more severe ...

Protein degradation in the cell can be carried out by an enzyme complex called the proteasome. Writing in Nature, Goldberg et al. 1 reveal that the proteasome is more than just a protein-degradation ...

For the first time, scientists have answered a longstanding question in cell biology about a partnership of proteins called ...

Thought too hard to do, a new platform evolved proteins in mammalian cells, which could help researchers design drugs that work better in humans. “There are many, many examples, both published and ...

For decades, the story of Alzheimer's research has been dominated by a battle between A-beta and tau amyloids, both of which can kill neurons and impact the brain's ability to function. A new study ...

All living things, including people, need zinc in their diets. Getting too little of this essential metal can impair growth and cause immune dysfunction, neurological disorders and cancer.

Researchers reveal structure of ancient viral protein appearing in breast cancer, lupus, and ALS, opening new paths for ...
