Deletion analysis of GAL4 defines two transcriptional activating segments

Cell. 1987 Mar 13;48(5):847-53. doi: 10.1016/0092-8674(87)90081-x.


We describe the activities of a wide array of deletion mutants of GAL4, a yeast transcriptional activator. We identify two short regions of GAL4, each of which activates transcription when fused to the DNA-binding region of the molecule. Very large portions of GAL4 are not required for gene activation.
