NUCLEIC ACID DIRECTING THE EXPRESSION OF A POLYPEPTIDE OF INTEREST IN THE POSTERIOR SERICIGENIC GLANDS OF A LEPIDOPTERAN AND ITS APPLICATIONS

摘要

The invention relates to a nucleic acid directing the expression of a protein of interest specifically in the cells of the posterior sericigenic glands ofBombyx mori. The invention also relates to an expression cassette comprising a polynucleotide of interest placed under the control of a nucleic acid such as described hereinbefore. The invention also relates to a recombinant integration vector comprising a nucleic acid or an expression cassette as defined hereinbefore as well as a host cell, modified by the integration of said nucleic acid or said expression cassette in its genome.
