Caption: Ataxin-7, one of several genes associated with neurodegenerative disease, anchors a key enzymatic module to the fruit fly SAGA complex, which helps control gene activity in organisms from yeast to humans. Fly polytene chromosome preparation with Ataxin-7 is shown in green, RNA polymerase in red and DNA in blue.
