N-Terminal Arginines Modulate Plasma-Membrane Localization of Kv7.1/KCNE1 Channel Complexes
Figure 6
Immunofluorescent studies of membrane representation.
Confocal images of HEK cells transfected with Kv7.1 and flag-tagged KCNE1 constructs. The top row localizes Kv7.1 (red) within cells. The middle row shows the distribution of KCNE1 (green), bottom panels illustrate the plasma-membrane marker pan-cadherin (blue). Bars represent 10 µm. The respective bar graphs below represent the mean±SEM data of Kv7.1 and KCNE1 correlation with plasma-membrane marker pan-cadherin. White bars represent Kv7.1/pan-cadherin ratio, hatched bars are KCNE1/pan-cadherin ratio. Results are from 4-9 experiments each. Cad – cadherin, other abbreviations as above.
