Membrane Fusion
Proteins Membrane Fusion Proteins (MFPs) are integral membrane proteins that play an essential role in cellular signaling, organelle biogenesis, and transport of macromolecules across biological membranes. They are highly conserved in all forms of life, featuring in processes such as exocytosis (the movement of substances from inside a cell to the outside), endocytosis (the movement of substances from outside a cell to the inside), and the fusion of intracellular organelles. By merging two different membranes, MFPs facilitate the exchange of lipids, proteins, and other macromolecules between the opposing sides. In addition, they can mediate the fusion of cells and viruses, and aid in the formation of membrane junctions which are essential for healthy development and function of cells. The study of MFPs is thus fundamental for understanding the molecular mechanisms underlying many physiological processes.
