Dpp-gal4 driver

However, unlike the MF associated pattern of dpp gene expression, the targeted dpp-Gal4 driver expression is restricted to the posterior margin of the developing eye disc. We screened GMR lines harboring regulatory regions of dpp fused with Gal4 coding region to identify MF specific enhancer of dppusing a GFP reporter gene.  · However, unlike the MF associated pattern of dpp gene expression, the targeted dpp-Gal4 driver expression is restricted to the posterior margin of the developing eye disc.

The standard expression system used in Drosophila is the bipartite GAL4–UAS system first described by Brand and Perrimon (). This elegant and robust approach relies on the availability of so-called GAL4 driver lines. These flies are often freely available from stock centers (http.

Scer\GAL4 www.doorway.ru drives expression along the lateral edges of the eye disc, and in a stripe medially across the antennal disc, roughly parallel to the morphogentic furrow of the eye disc. (Datta et al., ). The two other GAL4 drivers have more specific expression patterns: dpp-GAL4 is expressed along the anterior/posterior compartment boundary of each imaginal disc, and sev-GAL4 is expressed mainly in the eye imaginal discs. The dpp-Gal4 driver is expressed only in a subset of cells that express Dpp. Nevertheless, in dpp-Gal4, UAS-dpp RNAi larvae, the level of nuclear pMad in the PG is greatly reduced (Fig 6A and B). Thus, the Dpp that reaches the PG must be produced by cells with current or past expression of dpp-Gal4.

(I) A combined overexpression of Yki and Sd in the wing disc (dpp-Gal4, UAS-mitoGFP, the dpp-Gal4 driver, we found that combined inactivation. 2 ago fd5 regulation by btd and Sp1. (A) Control wing imaginal disc expressing GFP (green) under the dpp-Gal4 driver and stained for Dll (red) and Dac. In yeast, GAL4 is a protein that forms a dimer (two units bind together) and functions as a transcription activator. It binds to a specific DNA.
