Cellular membrane proteins play many important roles throughout the body, including transporting substances in and out of the cell, transmitting signals, speeding up reactions and helping neighboring ...

Protein function is often dynamically regulated by interactions with small molecules. Understanding the molecular mechanisms behind processes such as metabolic reactions and drug responses requires ...

How large, fully folded proteins can pass through cell membranes without destroying them has long been one of the open ...

When a cell receives a message from outside, it generates a molecule called cyclic AMP (cAMP) to relay this message. To ensure the signal reaches the correct effector without triggering pathways ...
