Plasma Membrane Markers

The cell membrane, also called the plasma membrane or plasmalemma, is a semipermeable lipid bilayer common to all living cells. It contains a variety of biological molecules, primarily proteins and lipids, which are involved in a vast array of cellular processes. It also serves as the attachment point for both the intracellular cytoskeleton and, if present, the cell wall.

The cell membrane surrounds the cytoplasm of a cell and physically separates the intracellular components from the extracellular environment, thereby serving a mechanical function similar to that of skin. This barrier is able to regulate what enters and exits the cell as it is selectively permeable - cells require a variety of substances to survive and the cell membrane serves as "gatekeeper" to what, and how much, enters and exits. The movement of substances across the membrane can be either passive, occurring without the input of cellular energy, or active, requiring the cell to expend energy moving it across the membrane.
