Every cell depends on proteins to function and stay healthy. These proteins are made inside the cell from amino acids, but ...

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 have discovered how unstructured segments of surface proteins regulate the biological function of a cell. Their study, published in Nature Communications, sheds new light on the interplay ...

Longevity science has spent decades chasing single molecules that might slow aging, but most candidates have delivered modest ...

Proteins are among the most important molecular building blocks of life. They are chains of amino acids assembled in our cells by ribosomes, the molecular "protein factories" of our bodies. The ...

Scientists at St. Jude Children's Research Hospital have characterized a hidden intermediate state at the center of Src kinase function. This hidden state allows the kinase to repeatedly modify its ...

New clue to obesity: The protein that's driving your cells to hold more fat By Bronwyn Thompson November 25, 2025 Scientists find a key protein that forces fat cells to take on excess baggage ...

A protein found in our cells has emerged as a secret weapon against biological aging, acting like a glue to repair damaged DNA and ward off neurological degeneration including that seen in motor ...

Researchers at UT Southwestern Medical Center have identified a protein that causes human cell membranes to break open in a form of inflammatory programmed cell death called necroptosis. Their ...
