A plasma membrane is permeable to specific molecules that a cell needs. Transport proteins in the cell membrane allow for selective passage of specific molecules from the external environment.

Scientists have revealed the secret to the structural integrity of tiny particles that transport cargo from ... by EVs with and without the membrane protein to mice with ailing hearts.

Membrane transport proteins are specific and selective for ... In contrast to prokaryotes, eukaryotic cells have not only a plasma membrane that encases the entire cell, but also intracellular ...

Based on the mechanism of intracellular transport of membrane proteins revealed in this study ... two homologs mediate endoplasmic reticulum-to-plasma membrane traffic of boric acid channels.

This takes place when molecules diffuse across the cell membrane by travelling through specific transport proteins. It occurs down a concentration gradient - molecules move from an area of high to ...

By analyzing E. coli protein levels, scientists found a surplus of membrane shuttle proteins that may play a role in antibiotic resistance.

The plasma membrane has distinct regions called membrane microdomains, which have different lipid and protein compositions ... that affect signaling or transport functions. The researchers ...

In an earlier study, the researchers demonstrated that "early endosomes," which primarily function to transport substances ... "Impaired plasma membrane repair plays a crucial role in the ...
