split-ubiquitin assay

Go to external page http://purl.obolibrary.org/obo/OBI_0001668


A binding assay that screens membrane soluble proteins by fusion of two integral membrane proteins (bait and prey) to two different ubiquitin moieties. One moiety is also fused to a transcription factor (TF) that can be cleaved off by ubiquitin specific proteases. Upon bait and prey interaction, Nub and Cub-moieties assemble, reconstituting the split-ubiquitin. The reconstituted split-ubiquitin molecule is recognized by ubiquitin specific proteases, which cleave off the reporter protein, allowing it to induce the transcription of reporter genes.
