ADP-ribosylation factor 3 commonly known as ARF3 is a small GTP-binding protein with a mass of approximately 20 kDa. It belongs to the ARF family and is expressed in many tissues especially within cellular compartments that are highly dynamic including the Golgi apparatus and the cytoplasm. ARF3 functions by binding and hydrolyzing GTP which is an important function in regulating vesicular trafficking and membrane lipid metabolism.
Biological function summary
The functions performed by ARF3 revolve around the regulation of vesicle formation and trafficking within cells. It is critical in the formation of COPI-coated vesicles and is involved in the retrieval pathway of membrane proteins between the Golgi and endoplasmic reticulum. ARF3 interacts closely with proteins like coatomer and ARF-GEFs (guanine nucleotide exchange factors) to facilitate these processes. As part of its biological activity ARF3 affects the recruitment of various effector proteins necessary for the vesicular transport.
Pathways
ARF3 plays significant roles in the regulation of intracellular transport pathways and lipid signaling pathways. It interacts with proteins involved in the phosphatidylinositol signaling pathway influencing membrane dynamics and cell signaling. ARF3's function aligns it closely with proteins such as phosphatidylinositol 4-kinases which are key in modifying phosphoinositides that are essential for membrane trafficking and signal transduction.
Connections between ARF3 and pathological conditions like cancer and neurodegenerative diseases have been observed. Abnormal expression or mutation of ARF3 may lead to disruptions in membrane trafficking contributing to disease progression. ARF3 has shown links with proteins such as RAB proteins in the context of cancer as they collaboratively affect cellular processes relevant to tumor progression such as cellular migration and invasion.
