HEMOCYTE-SPECIFIC PROMOTER AND ITS CORE ACTIVE REGION OF BOMBYX MORI FOR REGULATION OF TISSUE-SPECIFIC STAGE GENE EXPRESSION

摘要

PURPOSE: A promoter of a hemocyte-specific expression gene and a promoter active region are provided to obtain a recombinant protein and to save cost and time for developing a silk worm transformant which produces the recombinant protein. CONSTITUTION: A promoter of a hemocyte-specific expression gene is isolated from silk worm and is denoted by sequence number 1. The sequence of sequence number 1 has 579 bp. A promoter active region of the gene contains the promoter of hemocyte-specific expression gene. A method for transforming a silk worm comprises a step of using the promoter. A silk worm transformant is prepared using the promoter and produces recombinant protein.
