Rab proteins
Rab proteins are a group of small GTPase proteins that play a crucial role in cellular transport. They act like traffic signs, directing the movement of vesicles—small sacs that carry molecules within cells. Each Rab protein is responsible for specific routes and destinations, ensuring that important substances are delivered to the right place at the right time. These proteins are vital for processes such as secretion, nutrient uptake, and recycling of cellular materials, thus contributing to the overall functioning and health of cells. Abnormalities in Rab proteins can be linked to various diseases.

Rab proteins are a family of molecules that play a crucial role in the transport of materials within cells. They act like traffic directors, helping to guide vesicles (small packages of proteins and other substances) to their correct destination, ensuring proper cellular function. By attaching to specific areas on membranes, Rab proteins facilitate the fusion and movement of these vesicles, which is essential for processes such as nutrient uptake and cell communication. Their proper functioning is vital for maintaining healthy cells, and dysfunction in Rab proteins is linked to various diseases, including neurodegenerative disorders.
