  • The BID transgene is under GAL4 UAS control. Six independent fly lines were generated and tested by crossing to GAL4-producing driver lines. Line names indicate the chromosome that the transgene is on followed by a letter for each independent insertion found; each line has a single insert. da-GAL4: GAL4 protein produced under control of the daughterless promoter, ubiquitous expression. ey-GAL4: GAL4 protein produced under control of the eyeless promoter, eye imaginal disc expression. The phenotypes correlate with the level of BID expression, as determined by semiquantitative Western blots.
