ubiquitin reconstruction mammalian membrane two hybrid A membrane bait protein is tagged with the C-terminal half of ubiquitin (Cub) and a chimeric transcription factor, and a cytosolic or membrane-bound prey is tagged with the N-terminal half of ubiquitin (Nub). Upon interaction of bait and prey, the split halves form pseudoubiquitin, which is recognized by cytosolic deubiquitinating enzymes, resulting in cleavage of the transcription factor and expression of a reporter gene.
