Researchers of the Hong Kong University of Science and Technology (HKUST) recently uncovered a novel molecular mechanism that regulates the subcellular localizations of Arf proteins, shedding light on the mechanism underlying various inherited diseases and offering new insight to the treatment of them.
The small GTPases of the ADP-ribosylation factor (Arf) family are key initiators of various physiological processes including secretion, endocytosis, phagocytosis and signal transduction. Arf family proteins function to mediate recruitment of cytosolic effectors to specific subcellular compartments. This process facilitates Arf effectors to perform cargo recognition, lipid modification or other cellular functions. Read More...
