title: Deletion analysis of GAL4 defines two transcriptional activating segments.
abstract: 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.
