GAL4 activates gene expression in mammalian cells

H Kakidani, M Ptashne - Cell, 1988 - cell.com
Results GAL4, a protein that activates transcription in yeast, is shown to activate the mouse

Mutants of GAL4 protein altered in an activation function

G Gill, M Ptashne - Cell, 1987 - cell.com
Activating region I of GAL4 has been defined as a region 48 amino acids long which, when
attached to GAL4's DNA-binding domain, activates transcription in yeast. Here we describe …

A eukaryotic transcriptional activator bearing the DNA specificity of a prokaryotic repressor

R Brent, M Ptashne - Cell, 1985 - cell.com
We describe a new protein that binds to DNA and activates gene transcription in yeast. This
protein, LexA-GAL4, is a hybrid of LexA, an Escherichia coii repressor protein, and GAL4, a …

E Giniger, M Ptashne - … of the National Academy of Sciences, 1988 - National Acad Sciences
The yeast transcriptional regulatory protein GAL4 binds to four sites in the GAL upstream
activating sequence and stimulates transcription of the adjacent GAL1 and GAL10 genes …

Negative effect of the transcriptional activator GAL4

G Gill, M Ptashne - Nature, 1988 - nature.com

promoters, and stimulate transcription of nearby genes (1). Separable functional elements of …

Yeast activators stimulate plant gene expression

J Ma, E Przibilla, J Hu, L Bogorad, M Ptashne - Nature, 1988 - nature.com
GAL4 is a transcriptional activator found in yeast1, 2. Two distinct functions of the protein are
required for its activity3–5: one directs sequen1ce-specific DNA binding, and another …

Deletion analysis of GAL4 defines two transcriptional activating segments

J Ma, M Ptashne - Cell, 1987 - cell.com
We describe the activities of a wlde array of deletion mutants of GAL4, a yeast transcriptional
activator. We identify two short regions of GAL4, each of which activates transcription when …

The hormone-binding domains of the estrogen and glucocorticoid receptors contain an inducible transcription activation function

NJG Webster, S Green, JR Jin, P Chambon - Cell, 1988 - cell.com
