Supplementary information

Rab5 also known as Ras-related protein Rab-5A is a small GTPase of approximately 24 kDa. It is part of the Rab family of proteins and functions as an endosomal marker in cells. Rab5 is ubiquitously expressed but shows enriched expression in tissues with a high rate of endocytosis like the brain and liver. This protein plays a significant role in early endosome fusion and trafficking acting as an essential regulator of vesicular transport processes within the cell.
Biological function summary

Rab5 regulates the early endocytic pathway by mediating vesicle docking and fusion processes. It is not a part of a large complex but interacts with a range of effector proteins that facilitate endosome maturation. Rab5's role as an endosomal marker makes it important for membrane trafficking receptor recycling and signal transduction. Researchers often identify Rab5 in cellular studies using endosome staining techniques or specific antibodies like Drosophila antibodies to visualize its function and distribution.

Pathways

The endocytic network heavily involves Rab5 particularly influencing the endocytosis and endosomal signaling pathways. It frequently interacts with proteins such as EEA1 (Early Endosome Antigen 1) and Rabaptin-5 which are critical for endosomal membrane fusion. This mechanistic involvement ensures the correct transfer and processing of endocytic vesicles facilitating the continual cycle of membrane and receptor turnover in cells.

Rab5 dysfunction associates with neurological conditions such as Alzheimer's disease and cancer. Alterations in Rab5 levels or function can disrupt normal endosomal trafficking leading to amyloid beta peptide accumulation in Alzheimer's. Additionally Rab5's role in cancer relates to its regulation of growth factor receptors where its interaction with proteins like the PE marker influences tumor progression. Understanding Rab5 pathways and interactions paves the way for developing targeted therapeutics in these disorders.

Target data

Small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins to regulate cellular responses such as of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Active GTP-bound form is able to recruit to membranes different sets of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. RAB5A is required for the fusion of plasma membranes and early endosomes (PubMed : 10818110, PubMed : 14617813, PubMed : 15378032, PubMed : 16410077). Contributes to the regulation of filopodia extension (PubMed : 14978216). Required for the exosomal release of SDCBP, CD63, PDCD6IP and syndecan (PubMed : 22660413). Regulates maturation of apoptotic cell-containing phagosomes, probably downstream of DYN2 and PIK3C3 (By similarity).
