Fig. 5From: PA-6 inhibits inward rectifier currents carried by V93I and D172N gain-of-function KIR2.1 channels, but increases channel protein expressionPA-6 treatment for 24 h induces intracellular KIR2.1 accumulation of WT, V93I and D172N channel proteins in HEK293T cells. Confocal microscopy optical slices (0.7-0.8 μm) displaying KIR2.1 (green) localization in HEK293T cells transfected with WT, V93A and D172N channels under control conditions and following 24 h of PA-6 (1 and 5 μM). Cadherin (red) co-staining identifies the position of the plasma membrane. DAPI (blue) is used to visualize nuclei. Scale bars represent 10 μmBack to article page
