Abstract
The present invention relates to a system for producing a protein of interest in a host cell comprising the combined use of two expression cassettes, one of which is for expressing a useful DNA fragment controlled by a thiamine-regulable promoter region, while the other is for expression an activator gene. The present invention also concerns expression cassettes comprising a useful DNA fragment controlled by a promoter region derived from the Schizosaccharomyces pombe pho-4 gene, as well as the vectors and cells comprising such an expression cassette. A novel method for the production of a useful protein is also provided.
