Cell Adhesion: They facilitate the binding of cells to one another and to the extracellular matrix. Immune System: Glycoproteins are key components of the immune response, as seen in antibodies and cell surface antigens. Signal Transduction: Many receptors involved in signaling pathways are glycoproteins. Protein Stability: The carbohydrate moiety can protect the protein from degradation. Cell Recognition: Glycoproteins on the cell surface are involved in recognizing and binding to specific molecules.
