The human potassium (HERG) channel is encoded by the ether-à-go-go-related gene (herg), and its activity may be regulated by association with other cellular proteins. To identify cellular proteins that might play a role in the regulation of the HERG channel, we screened a human heart cDNA library with the N terminus of HERG using a yeast 2-hybrid system, and identified caveolin-1 as a potential HERG partner. The interaction between these 2 proteins was confirmed by coimmunoprecipitation assay, and their overlapping subcellular localization was demonstrated by fluorescence immunocytochemistry. The physiologic implication of the protein-protein interaction was studied in whole-cell patch-clamp electrophysiology experiments. A significant increase in HERG current amplitude and a faster deactivation of tail current were observed in HEK293/HERG cells in a membrane lipid rafts disruption model and caveolin-1 knocked down cells by RNA interference. Alternatively, when caveolin-1 was overexpressed, the HERG current amplitude was significantly reduced and the tail current was deactivated more slowly. Taken together, these data indicate that HERG channels interact with caveolin-1 and are negatively regulated by this interaction. The finding from this study clearly demonstrates the regulatory role of caveolin-1 on HERG channels, and may help to understand biochemical events leading to arrhythmogenesis in the long QT syndrome in cardiac patients."xsd:string |
