FUSION PROTEIN FOR SECRETORY PROTEIN EXPRESSION

摘要

There is provided a fusion protein suitable for secretion of more than one polypeptide(s) of interest (POI) comprising a signal peptide, a POI, a passenger domain comprising a beta stem domain from an autotransporter protein, and a translocator domain from an autotransporter protein, wherein the beta stem-forming sequence of the passenger domain is essentially intact and the POI(s) is/are fused to the beta stem domain.
