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 ...

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 ...

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 ...

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

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 ...

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

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 ...

Researchers at ETH Zurich recently explained the role of a molecular complex that orchestrates the production of proteins in ...

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

Unlike our organs, cell organelles such as mitochondria are not fixed in place, but when, where, how, and why organelles move ...
