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

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 ...

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 ...

Calcium (Ca2+) drives many cellular functions, though the way it controls quality of proteins in the endoplasmic reticulum ...

Scientists have long been trying to tease apart hepatitis A virus, to understand its inner workings and how it functions in the human body. Infectious disease researchers have discovered that a little ...

Delivering a connection-building protein to star-shaped cells in the brain could reverse changes to neural circuits seen in ...

As we age, our immune system quietly loses its edge, and scientists have uncovered a surprising reason why. A protein called ...

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 ...
