True about caveolin:
Caveolins are proteins that interact with cholesterol and polymerize to form the caveolae (flask-shaped membrane depressions). These are prominent in endothelial cells, where they help in the uptake of nutrients from the blood. These are involved in cholesterol regulation and transcytosis.
