Pheromone - inducible yeast promoter

摘要

A yeast promoter inducible by the appropriate pheromone and a method of expressing a gene of interest in substantial quantities by placing it under the control of the inducible promoter. DNA encoding a protein of interest is fused or linked to a pheromone - inducible yeast promoter, such as the FUSI or the FUS2 promoter, and the fusion is inserted onto a high copy vector; the resulting product is introduced into wild type yeast cells. Stimulation of these yeast cells by the appropriate pheromone results in induction of transcription of the yeast promoter and expression of the protein of interest in substantial quantities.
