Cell permeable peptide that blocks eNOS (NOS III) activity and cellular nitric oxide (NO) release in vitro and reduces inflammation and tumorigenesis in vivo. Caveolin-1 interacts with several lipid-modified signalling ligands, such as EGFR, eNOS, G-protein α-subunits, PKCα, H-Ras, and Src, via the C1-SD82-101 sequence.
