Fibroin Heavy chain Core Promoter of Bombyx mori and the Vector Thereof

摘要

The present invention relates to a high expression promoter of a fibroin heavy chain gene of silkworm, a recombinant vector containing the promoter, and a method for producing silk-specific foreign protein using the same. The core promoter derived from the fibroin heavy chain gene according to the present invention and the high expression vector containing the fibroin heavy chain gene according to the present invention have a small size and high transformation efficiency and can induce high expression in the silkworm or silkworm body than the conventional BmA3 promoter, It is very useful industrially because of the improvement of the productivity of the heterologous protein and the convenience of the purification process.
