Extended Data Fig. 1: Sample electron density from the cereblon-DDB1-SALL4 ZF2-pomalidomide crystal structure.
From: Crystal structure of the SALL4–pomalidomide–cereblon–DDB1 complex

Fo-Fc electron density map calculated in the absence of pomalidomide and contoured at 3σ following a round of refinement. Protein atoms are not shown in the figure.
