GAL4 UASG 1 In the absence of galactose, GAL80 blocks GAL4 from GAL80 activating transcription. TATA Basal transcription apparatus GAL3 Galactose GAL4 TATA 3 GAL4 can now interact with basal transcription apparatus and stimulate transcription. GAL80 GAL3 2 When galactose is present, it binds to GAL3 and brings about a change in the conformation of GAL80. Galactose 17.7 Transcription is activated by GAL4 in response to galactose.
