Protein molecules are found embedded in the two layers of phospholipids. Membrane proteins have a wide variety of functions. Some allow a cell to respond to specific chemical signals from other cells, ...

Cells are the smallest unit of life and the building blocks for all organisms. Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell ...

All cells are encapsulated by a lipid membrane that facilitates their interactions with the environment. How cells manage diverse mixtures of lipids, which dictate membrane property and function, is ...

The endosomal sorting complex required for transport (ESCRT) is a multicomplex machinery comprising proteins that are conserved from bacteria to humans and has diverse roles in regulating the dynamics ...

Artificial cells created in the laboratory offer a wide range of potential applications. Until now, however, their membranes—unlike those of real cells—have been virtually impermeable. Researchers at ...
