Cell Membrane

The cell membrane, also known as the plasma membrane, is a biological membrane that surrounds the cytoplasm of all living cells. It acts as a selective barrier, controlling the movement of substances in and out of the cell. Its structure is primarily a phospholipid bilayer with embedded proteins and cholesterol. It plays critical roles in cell communication, structural support, and maintaining cell potential. While not a direct drug target itself, many drugs interact with its components.

Varies depending on the specific drug and target. Some drugs disrupt membrane integrity, while others bind to membrane-bound receptors or proteins to modulate cellular signaling.
