Abstract Caveolin, the protein of the caveolar membrane, interacts and binds with endothelial nitric oxide synthase (eNOS), forming a caveolin-eNOS complex leading to suppression of the eNOS activity. Caveolin, therefore, maintains eNOS in the inactivated state leading to reduced nitric oxide (NO) produc...
