Integral membrane proteins

Integral membrane proteins are proteins that are embedded within the cell membrane. They span across the membrane, which separates the inside of the cell from its outside environment. These proteins play crucial roles in various functions, such as transporting substances in and out of the cell, acting as receptors for signaling molecules, and providing structural support. Because they are tightly integrated into the membrane, they often maintain their position and are essential for the cell's interactions and communication with its surroundings. Their unique structure allows them to perform these important tasks effectively.
