Figure 1. Overall folding of UP1. (a) Ribbon diagram of the
UP1 structure, viewed from the front (b-sheet side) of the
molecule. The conserved RNP-2 and RNP-1 submotifs are colored
cyan and purple, respectively. Red indicates the disordered
portion of the linker region; its placement is not based on
electron density, but was included for clarity. The N terminus
starts at Pro7, and the C terminus ends at Ser182. (b) Side view
of the overall folding of UP1. Diagrams were generated with the
Ribbons program [67].
