Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such ...

Crossing the membrane is a major challenge on the journey through the cell. Large biomolecules usually benefit from different transport strategies to overcome the lipid bilayer, so the design and ...

This Collection focuses on the mechanistic aspects of membrane carriers and current advances in the biochemical and biophysical characterizations in this field, as well presenting new research tools ...

The cycling of water across membrane transporters is an hallmark of the cell metabolism and is potentially of high diagnostic significance for the characterization of tumors and other diseases. A ...

Bile acids are essential for digestion, metabolism, and hormonal signaling. Their circulation between the liver and intestine, known as enterohepatic circulation, depends on a coordinated network of ...

The plasma membrane is what isolates the cell’s interior from its surroundings. It is made up of a lipid bilayer and other macromolecules, such as carbohydrates, glycoproteins, and membrane proteins, ...

Structure of the newly decoded protein found in the membrane of sperm cells. Colours mark the different units of the protein, which can be put together to make a functioning protein like the building ...
