(Top middle) A schematic diagram of the domain positions in the PolIIIα sequence. The domains are labeled and colored as follows: the PHP domain in yellow, the palm in magenta, the thumb in green, the fingers in light blue, the β binding domain in orange, and the CTD in red. (Center) Two orthogonal views of the surface of PolIIIα colored as in the schematic above. Ribbon diagrams of the individual domains are shown around the outside.
