Post-translational modification by SUMO is an important mechanism to regulate transcription. Sumoyla-tion has diverse effects on substrate activity, but in most cases reported to date sumoylation of transcription factors correlated with transcriptional repression. Here we describe general strategies to address how post-translational modification by SUMO regulates the activity of a DNA-binding transcription factor.
