Protein engineering of multi-modular transcription factor alcohol dehydrogenase repressor 1 (adr1p), a tool for dissecting in vitro transcription activationviocyte co-culture system
Studying transcription machinery assembly in vitro is challenging because of long intrinsically disordered regions present within the multi-modular transcription factors. One example is alcohol dehydrogenase repressor 1 (Adr1p) from fermenting yeast, responsible for the metabolic switch from glucose to ethanol. The role of each individual transcription activation domain (TAD) has been previously studied, but their interplay and their roles in enhancing the stability of the protein is not known.
