Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in. Unlike prokaryotes, ...

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 ...

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

LA JOLLA, CA— 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 ...

Dynamin is a protein that plays a central role in endocytosis—the process where cells internalize substances by wrapping them in cell membrane vesicles. For a vesicle to detach, the neck of the ...

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

The protein NINJ1 enables cells to break open during certain types of cell death. Modulation of physical forces on the membrane reveals how NINJ1 acts. To understand how cells rupture under force, the ...

Collaboration between researchers at the University of Geneva, Institut de biologie structurale de Grenoble, and the University of Fribourg has shown how lipids and proteins in cell membranes react in ...

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from cell to cell through blood vessels and bodily fluids: special proteins that keep their ...

UCLA scientists have characterized the structure and function of a key survival protein in breast cancer cells that helps ...
