摘要:
The invention concerns the expression in a baculovirus-insect cell system of receptors with seven transmembrane domains, in particular receptors coupled to proteins G, in particular olfactory receptors, under the transcriptional control of a promoter derived from the polyhedrin promoter by deletion of all or part of the region of said promoter extending from -1 to -12 positions relative to the initiation site of the polyhedrin translation.
