Although caveolae are well-characterized subdomains of glycolipid rafts, their distinctive
morphology and association with caveolins has led to their internalization being considered
different from that of rafts. In this review, we propose that caveolae and rafts are internalized
via a common pathway, caveolae/raft-dependent endocytosis, defined by its clathrin
independence, dynamin dependence, and sensitivity to cholesterol depletion. The
regulatory role of caveolin-1 and ligand sorting in this complex endocytic pathway are …
Although caveolae are well-characterized subdomains of glycolipid rafts, their distinctive morphology and association with caveolins has led to their internalization being considered different from that of rafts. In this review, we propose that caveolae and rafts are internalized via a common pathway, caveolae/raft-dependent endocytosis, defined by its clathrin independence, dynamin dependence, and sensitivity to cholesterol depletion. The regulatory role of caveolin-1 and ligand sorting in this complex endocytic pathway are specifically addressed.
