Synthesized NHis–Cx43 was integrated into liposomal membranes and formed a hemichannel pore of NHis–Cx43. Fluorescence intensity of Cx43/DOPC liposomes containing ANTS and NHis–Cx43/10 mol% nickel‐chelating liposomes, after addition of DPX. Each symbol denotes an individual data point showing ANTS permeability ( n = 3) and the line denotes the mean. ** p
