| 内容記述 | To clarify the recognition site of (S)-semotiadil in the Na+ channels, we employed photoaffinity labeling with (S)-[3H]-D51-4700, an azidophenyl derivative of (S)-semotiadil, to Na+ channel preparations from rat brains and porcine hearts, and the results were compared with those by (R)-enantiomer to skeletal muscle Ca2+ channel. Protease-digestion of the photolabeled Na+ channels followed by quantitative immunoprecipitation assay using a site-directed antibody, revealed that 10- and 13- kDa fargments of brain and cardiac Na+ channels, respectively, were located within the regions including IVS6. These regions are corresponding to the 8.3 kDa fragment photolabled by (R)-[3H]-D51- 4700 in the skeletal muscle Ca2+ channel. Interestingly, however, the photoincorporation of (S)-[3H]-D51-4700 into the Na+ channel was 2-3 times higher than that of (R)-isomer; and visa versa in the Ca2+ channels. |
