Caveolae are involved in numerous cellular functions:
Endocytosis: Caveolae mediate a form of clathrin-independent endocytosis, allowing for the internalization of specific molecules. Signal Transduction: They act as platforms for various signaling molecules, facilitating signal transduction pathways. Mechanotransduction: Caveolae help cells sense and respond to mechanical stress, by flattening out and absorbing membrane tension. Lipid Regulation: They play a role in the regulation and trafficking of lipids within the cell membrane.
