Figure 4. Model.
(A–D) Models how inorganic phosphate inhibits Dicer-2 from processing hairpin RNAs and how Loqs-PD removes this inhibitory effect. Models are shown for (A) Dicer-2 alone, (B) Dicer-2 + phosphate, (C) Dicer-2 + Loqs-PD, and (D) Dicer-2 + phosphate + Loqs-PD. The background colors of the panels (A-D) correspond to the colors used in Figures 2 and 3.
