 When the nascent endosome forms, the recruitment of cofilin by ClC-5 is a prerequisite for the localized dissolution of the actin cytoskeleton, thus permitting the endosome to pass into the cytoplasm.It is conceivable that at the cell surface, the large intracellular C-terminus of ClC-5 has a crucial function in mediating the assembly, stabilization and disassembly of the endocytic complex via protein–protein interactions.Therefore, ClC-5 may accomplish two roles in the receptor-mediated endocytosis
