Hierarchy of zone attributes. a Zone primary structures with proteins as pink shapes and lipids as circles with two tails or one tail attached to protein. b Secondary structures in either side or top ...

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 ...

A new imaging approach is shedding light on one of cell biology’s most elusive questions: how lipids are organized and sorted within membranes.

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...

Cell membranes cradle, protect, and gatekeep living cells. Membranes can even affect how a cell behaves. But membranes’ own erratic behavior has puzzled scientists for years. Turns out, it’s all about ...

In every living cell, there are membranes, and in every membrane there are proteins, each of which acts as a chemical gatekeeper. Rather than passively letting ions pass in and out of the cell, these ...

Lipid bilayers in mammalian membranes can have a more asymmetric composition than previously thought, new research shows. This lipid abundance asymmetry is enabled by the unique properties of ...

Modern cells are complex chemical entities with cytoskeletons, finely regulated internal and external molecules, and genetic material that determines nearly every aspect of their functioning. This ...

Dynamin assembles into a ring around the neck of a forming vesicle and utilizes GTP hydrolysis energy to constrict and sever the membrane. The simulation reveals that the dynamin ring expands (loosens ...

Cells may generate their own electrical signals through microscopic membrane motions. Researchers show that active molecular processes can create voltage spikes similar to those used by neurons. These ...
