A new study highlighting the importance of a large protein complex called the exocyst in cell growth, division and ...

Proteins are life's engines, powering processes like muscle movement, vision, and chemical reactions. Their environments—water, lipid membranes, or other condensed phases—are critical to their ...

Like a mosaic, the cell membrane is a complex structure made up of many different parts, such as proteins, phospholipids, and cholesterol. The relative amounts of these components vary from ...

In this diagram of G-protein-coupled receptor activation ... Note that both the alpha subunit and the beta-gamma complex remain tethered to the plasma membrane while they are activated.

Researchers have identified ancient proteins that may help explain how the first complex cells evolved from simpler ones over 15 billion years ago I ...

Integral membrane proteins carry out essential functions in the cell, and their activities are often modulated by specific protein-lipid interactions in the membrane. Here, we elucidate the intricate ...

This valuable study investigates how the proteins of the Cdv division system in Metallosphaera sedula archaea sequentially interact with curved membranes in vitro, extending our understanding of this ...
