Rab8

Rab8 is a small protein that functions as a molecular switch, helping cells organize and direct traffic within themselves. It plays a key role in transporting materials to the cell membrane, which is essential for processes like cell signaling, growth, and the formation of structures such as cilia. By controlling the movement and delivery of cargo, Rab8 ensures that cells maintain proper function and communication with their environment. Its activity is regulated by chemical signals, making it vital for normal cellular operation and tissue development.
