Membrane proteins are a diverse group of proteins that are embedded within or associated with biological membranes. These proteins play a crucial role in a wide range of cellular processes, including cell signaling, transport of molecules across membranes, and cell-cell interactions. Membrane proteins are also important drug targets, with around 60% of pharmaceutical drugs targeting these proteins. Studying membrane proteins is challenging due to their hydrophobic nature and dynamic interactions with the lipid bilayer of the cell membrane. Researchers use a variety of techniques, such as X-ray crystallography, nuclear magnetic resonance spectroscopy, and cryo-electron microscopy, to study the structure and function of membrane proteins. Understanding membrane proteins is essential for advancing our knowledge of cell biology and developing new therapies for various diseases.
