Gal4-Degron-Vp16

Gal4 protein binds to a Gal1 promoter while VP16 recruits transcription machinery promoting transcription to anything under the Gal1 promoter. The two must be co-localized to work as a transcriptional activator.

The degron protein domain when fused to a protein acts as a source of instability leading to degradation by the cell via ubiquitination.

This system can be used to compare the relative stabilities of proteins. A sequence for a protein inserted between the degron and VP16 will produce a fusion protein which acts as a transcriptional activator for anything under a Gal1 promoter. If the protein inserted is unstable it will be degraded by the cell and the Gal4-VP16 transcriptional activator will no longer function. If a quantifiable marker protein such as GFP is under Gal1 then the level of GFP output of the cell is related to the stability of the inserted protein.
