ADDITIONAL INFORMATION for GAL4

SUMMARY PARAGRAPH for GAL4

GAL4 encodes one of the best studied transcription factors in the explored universe (5, 6, 7). In the presence of galactose, Gal4p activates transcription of the GAL structural genes, which encode galactose metabolic proteins. Gal4p binds to a specific sequence, the UASG, in the promoters of GAL structural genes. The transcriptional regulation of yeast GAL genes has been thoroughly reviewed in reference 7.

Among the promoters regulated by Gal4p is the one shared by the divergently transcribed genes GAL1 (encoding galactokinase) and GAL10 (an epimerase) (8, 7). The GAL1-GAL10 promoter has been widely used to conditionally overexpress genes in yeast (for example, see reference 9).

The DNA binding domain of Gal4p can be physically separated from its transcription activation domain (7). Many versions of the yeast two-hybrid, or interaction trap, method, use the Gal4p DNA binding and transcription activation domains (reviewed in reference 10).
