Figure 1 (image) RIKEN Share Print E-Mail Caption dATF-2 is essential for heterochromatin formation. In the Drosophila line, in which the white gene required for the production of red eye pigment is located close to the heterochromatin, the white gene expression is silenced by heterochromatin, leading to white eye (left). In the dATF-2 mutant, the heterochromatin is disrupted, leading to red eye (right).
