Extended Data Fig. 7. Comparison of Noc1-Noc2, Noc2-Noc3 and Noc4-Nop14 heterodimers in yeast.

Extended Data Fig. 7

The evolutionarily related helical repeat heterodimers involved in ribosome biogenesis reveal similar structural composition. (a) Noc1-Noc2 heterodimer structure has the unique ability to bind to and chaperone an RNA helix structure (helix 2); zoomed inset shows a rotated view. (b, c) In comparison, the yeast Noc2-Noc3 heterodimer and the Noc4-Nop14 heterodimer are both unable to bind RNA in a similar fashion owing to steric hinderance from loops in the central cavity, highlighted with darker color.
