Patent ID: 7794974

Claim:
An isolated polypeptide having transcriptional activity on a protease promoter, wherein said polypeptide is selected from the group consisting of: (a) a polypeptide comprising the amino acid sequence of SEQ ID NO: 3; (b) a polypeptide comprising a peptide fragment, said peptide fragment having at least 80% sequence identity with SEQ ID NO: 22; (c) a polypeptide comprising peptide fragments, said peptide fragments having at least 80% sequence identity with both SEQ ID NO: 22 and SEQ ID NO: 4; and (d) a polypeptide comprising (i) an amino acid sequence which has at least 90% sequence identity with the amino acid sequence of SEQ ID NO: 3 and comprising (ii) a peptide fragment, said peptide fragment comprising the amino acid sequence EWAHL(X) 5-20 ST, wherein “X” represents any amino acid and the range 5-20 represents the number of “X” found.
