Rab9

Rab9 is a protein involved in cellular transport, specifically guiding vesicles—tiny sacs that carry materials—between the Golgi apparatus and late endosomes in cells. Think of it as a molecular courier that ensures certain cargo, like enzymes or other molecules, are sent to the right location within the cell. Rab9 switches between active and inactive states to regulate this traffic, helping cells maintain proper function and communication. Understanding Rab9 is important because disruptions in this process can impact cell health and are linked to diseases like neurodegeneration and certain infections.
