(a) Domain organization of ATX. (b) Ribbon diagram of the ATX structure in the free form. (c) Surface representation of the ATX structure in the free form. Somatomedin B-like domain 1 (SMB1), orange; SMB2, brown; core subdomain, cyan; insertion (Ins) subdomain, pale cyan; nuclease-like domain (NLD), magenta; L1, beige; L2, yellow-green; EF hand–like motif, pink. N-glycans and sulfate ion are shown as yellow and orange sticks, respectively. Zn2+, Ca2+, Na+ and K+ ions are shown as gray, green, purple and blue spheres, respectively. All 15 disulfide linkages are shown as sticks.

This diagram shows the setup for an imaging method that mapped electrical signals using a sheet of graphene and an infrared laser. The laser was fired through a prism (lower left) onto a sheet of graphene. An electrode was used to send tiny electrical signals into a liquid solution (in cylinder atop the graphene), and a camera (lower right) was used to capture images mapping out these electrical signals.
