When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ...

Located at the cellular interface, membrane proteins play critical regulatory roles in the signaling between a cell and its interacting environment, making them popular and ideal drug targets.

Many biological processes are regulated by electricity—from nerve impulses to heartbeats to the movement of molecules in and ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular ...

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 ...

Membraneless organelles, also called biomolecular condensates, are changing how scientists think about protein chemistry, ...

The chemical reactions on which life depends need a place to happen. That place is the cell. All the things which biology recognises as indisputably alive are either cells or conglomerations of cells ...

Scientists have discovered that T cell receptors activate through a hidden spring-like motion that had never been seen before ...

Researchers at UT Southwestern Medical Center have identified a protein that causes human cell membranes to break open in a ...
