a Distribution of charged residues, shown in stick representation, in the transmembrane helices indicates a curved transmembrane region. Only two opposing MSL1 subunits are shown for clarity. b The pore structure. Residues lining the pore are highlighted in stick representation. c The pore profile of MSL1 (blue). Also shown are the pore profiles of the closed (black, PDB: 6RLD) and open (gray, PDB: 2VV5) EcMscS structures.
