Caveolin-1 scaffolding domain peptide (C1-SD82-101) fused at the N-terminus to the cell-permeable Antennapedia internalization sequence (43-58). This peptide is reported to block eNOS activity and cellular NO release in vitro and reduce inflammation and tumorigenesis in vivo. Caveolin-1 interacts with several lipid-modified signaling ligands, such as EGFR, eNOS, G-protein α-subunits, PKCα, H-Ras, and Src, via the C1-SD82-101 sequence.
