Abstract
Clathrin-independent endocytosis removes membrane receptors and other proteins from the cell surface, yet the mechanisms controlling this process remain unclear. Galectin-3 is now shown to regulate the biogenesis of a subpopulation of clathrin-independent carriers (CLICs). Galectin-3 binds to glycosylated cargo proteins and interacts with membrane glycosphingolipids to induce membrane deformation and CLIC formation.
