Popis: The human bradykinin B2 receptor (B2R) fused with green fluorescent protein (GFP) at the C-terminal has been expressed in the methylotrophic yeast Pichia pastoris. In the expression vector, B2R gene was driven under the highly inducible promoter of alcohol oxidase 1 gene of P. pastoris. By fluorescence activated cell sorting (FACS) analysis and Western blot analysis, it was proved that B2R recombinant receptor proteins were expressed at a high level in the yeast. Furthermore, the transformants of P. pastoris were monitored with confocal microscopy, a strong green fluorescence was checked out. The recombinant B2R receptor proteins were mainly located on the plasma membrane proved by immunofluorescence microscopy.
