Trafficking of the intracellular vesicles and membrane protein incorporated in the vesicles is essential for a variety of basic biological processes. Growing evidence has highlighted the importance of the actin cytoskeleton in the trafficking of synaptic vesicles, secretory granules, transporters, and channels including aquaporin. These trafficking processes require actin remodeling, which is spatiotemporally regulated. Recent researches have come to focus on the motility mechanism of the translocation. In this review, we describe the role of actin at each step of intracellular reservation, exocytosis, docking, fusion with the plasma membrane, and endocytosis, focusing on aquaporin-2 trafficking.

    F-actin remodelling is essential for a wide variety of cell processes. It is important in exocytosis, where F-actin coats fusing exocytic granules. The purpose of these F-actin coats is unknown. They may be important in stabilizing the fused granules, they may play a contractile role and promote...

    Research done in the last years strongly support the hypothesis that PIP aquaporin can form heterooligomeric assemblies, specially combining PIP2 monomers with PIP1 monomers. Nevertheless, the structural elements involved in the ruling of homo versus heterooligomeric organization are not...
