Caveolin mediated endocytosis begins with the clustering of caveolin proteins in the plasma membrane. These clusters form caveolae, which are flask-shaped invaginations. Upon receiving specific signals or binding to certain ligands, these caveolae pinch off to form vesicles that are transported into the cell. Inside the cell, these vesicles can fuse with other organelles like endosomes or the Golgi apparatus, where their cargo is processed.
