Rab5

Rab5 is a protein that acts like a traffic coordinator inside cells, specifically managing early endosomes—small vesicles that transport and sort materials from the cell surface. It helps these vesicles form, move, and fuse with other compartments, ensuring molecules like nutrients or signals are properly processed or directed elsewhere. Rab5 is essential for maintaining cellular organization and function, playing a key role in processes such as cell signaling, nutrient uptake, and membrane recycling. Its activity is carefully regulated to keep the cell functioning smoothly.
