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 ...

Understanding the best ways to get a membrane protein to its destination in a cell is crucial, and the best method to make this happen is still unclear. Cell-free systems allow for interactions ...

Scientists have uncovered new details about how cells manage the distribution of lipids in their cell membrane. These lipids, known as phospholipids, are arranged in a bilayer of membranes, regulating ...

Cellular membrane proteins play important roles in cellular transport, signaling, and cell-to-cell communication. Malfunction in membrane proteins can lead to serious diseases, such as cancer. However ...

In the evolutionary history of life, the ability of a cell to separate its inner world from the external environment was an important turning point. The so-called plasma membrane lets cells control ...

Researchers discovered that immune-related proteins form membrane-bound rings that help regulate cell death signals, ensuring ...

The Golgi apparatus transports and modifies proteins in eukaryotic cells. How have scientists studied dynamic protein movements through the Golgi? One of the principal observations by Rothman's group ...

A lipid hidden within cells called phosphatidylserine reveals how the body initiates the removal of threats and cellular debris.
