1.A.2.2.2
The KirBac3.1 K+ channel (a dimer of dimers with gating visualized by atomic force microscopy, Jaroslawski et al., 2007) (regulated by binding lipids, G-proteins, nucleotides, and ions (H+, Ca2+, and Mg2+)). The 3-D structure is available (1XL6_A).  The inhibitory cholesterol binding site has been identified (Fürst et al. 2014).
