Transporters carry a molecule (such as glucose) from one side of the plasma membrane to the other. Receptors can bind an extracellular molecule (triangle), and this activates an intracellular process.

Membrane proteins and membrane lipids are essential partners in various biological processes, and elucidating their ...

Unusual proteins that can quickly fold into different shapes provide cells with a novel regulatory mechanism. Proteins are molecular origami at its finest. Classically, a protein is imagined as a ...

Plant-based sources of protein are often deemed inferior to animal-based ones, as the former is said to contain “incomplete” proteins. This causes many to fear they may be getting the wrong type or ...
