GAL4-VP16 transcription activator CDS, compatible with PlantSyntax (RFC105)

GAL4 transcription activator. Binds to the UAS (upstream activation site) for activation of reporter expression in eukaryotes.

This part has been codon optimized for plant expression.

Usage and Biology

GAL4 is a transcription activator which is active in many eukaryotes. It can be used to amplify sensitive inputs. This particular part contains a VP16 fusion to enable the activator to enter the nucleus in plants.

By using an enhancer trap with GAL4, lines can be produced with very specific expression patterns (for example, expression active in a particular tissue). Further circuits utilising reporters driven by the UAS then inherit expression patterns. For example uses, see:

This part is Plant Syntax (RFC105) compatible, and can be used as a CDS part.
