| Description | Bait protein is fused to a standard protein fusion tag and an intein fragment, prey a with a different protein fusion tag and the complementary intein fragment. The bait and prey are co-expressed in a cell line where the association of bait and prey brings the intein fragments into close proximity, allowing them to reconstitute a fully functional intein, which then catalyzes its own excision and the concurrent ligation of the bait and the prey peptides (as well as the standard protein fusion tags). The resulting spliced protein can be resolved by regular western blot analysis due to its altered mobility, while the presence of the standard protein fusion tags allows visualization or purification of protein using regular biochemical techniques. | Namespace | PSI-MI |
