Disclosed is a method for expression of proteins of a two hybrid system, wherein said two hybrid system comprises a bait protein and a candidate prey protein, said method comprising the steps of: providing a host cell into which has been introduced an expression vector encoding a polyprotein comprising a bait protein portion and a candidate prey protein portion, said portions separated by a cleavable segment comprising a self-processing cleavage sequence, a signal peptide sequence or a protease cleavage site; and culturing the host cell under conditions which allow expression of the polyprotein and self processing or protease cleavage of the polyprotein. |
