Fig. (1) Structure of CSD. The association of caveolin-1 (thick
black line) with membranes (parallel lines) is shown. Note that
CSD is found at the surface of the membrane about midway
between the N-terminal (N) and C-terminal (C) ends of caveolin-1.
The combined amino acid sequence of the Antennapedia
internalization sequence (Antennapedia) which carries CSD across
membranes and into cells and of CSD is shown in single-letter
code.
