Fig. 7. Alignment of the human K2P channels using residues 69–84 from TRAAK as reference. Residues aligned to the triad F72-H76-E83 are colored in yellow. Residues aligned to R69 and E83 are colored in green. Cysteine residues aligned to C78 are colored in cyan. Residues aligned to the hydrophobic tetrad F72-L73-V79-L84 are inside red boxes.
