Cell surface glycoproteins

Cell surface glycoproteins are proteins found on the outer membrane of cells that have sugar molecules attached to them. These sugar chains help cells communicate, identify each other, and interact with their environment. They are essential for processes like immune response, cell signaling, and tissue formation. By serving as markers, glycoproteins enable the immune system to distinguish between healthy cells and foreign invaders. Their structure and modifications can affect how cells respond to signals and interact with each other, making them vital for proper cellular function and communication.
