WebApr 14, 2024 · The Gal4-UAS system is a way of manipulating gene activity widely used to study neurons in fruit flies. The system consists of two parts: a protein that can bind DNA and control the activity of genes (Gal4); and a genetic sequence (the UAS) that tells Gal4 where to bind and therefore which genes to activate. WebHow does it work? 1 fly with a Gal4 protein introduced upstream of an enhancer found in specific tissues is crossed with a fly with a UAS sequence added next to a reporter gene (etc.). The offspring show that when the enhancer gene is switched on/up, the reporter gene is switched on/up due to Gal4 binding to UAS in specific tissues.
