RAB5C Human

RAB5C is a member of the RAS oncogene family, which is a group of small GTPases involved in various cellular processes. These proteins play a crucial role in the regulation of intracellular vesicle trafficking, ensuring the fidelity of docking and fusion of vesicles with their correct acceptor compartments .

The RAB5C gene is located on chromosome 17 and encodes a protein that is part of the Rab family of small GTPases. These proteins are involved in the regulation of endocytic pathways and are essential for the proper functioning of cellular transport mechanisms . The RAB5C protein is known for its role in vesicular traffic, particularly in the early stages of endocytosis .

RAB5C, like other Rab proteins, functions as a molecular switch that cycles between an active GTP-bound state and an inactive GDP-bound state. In its active form, RAB5C interacts with various effector proteins to facilitate the docking and fusion of vesicles with target membranes . This process is critical for the transport of proteins and lipids within the cell, as well as for the recycling of membrane components .

Mutations or dysregulation of RAB5C and other Rab proteins have been implicated in various diseases, including cancer and neurodegenerative disorders. For instance, RAB5C has been identified as a candidate gene for type-2 diabetes risk, with a functional role in endosomal trafficking . Additionally, its involvement in vesicular traffic makes it a potential target for therapeutic interventions in diseases where cellular transport is disrupted .

Recombinant RAB5C protein is widely used in research to study its function and interactions with other cellular components. It is also utilized in various assays to investigate the mechanisms of vesicle trafficking and the role of Rab proteins in cellular processes . Understanding the function of RAB5C and its interactions can provide insights into the development of novel therapeutic strategies for diseases associated with vesicular transport dysfunction .
