Polypeptide for unstabilizing protein in cells under aerobic conditions and DNA encoding the same

摘要

To identify a domain in HIF-1α protein, which participates in stabilization of a fused protein, DNA encoding the following polypeptide (A) or (B) is provided: (A) a polypeptide having the amino acid sequence of SEQ ID NO: 1 (B) a polypeptide having an amino acid sequence comprising at least 16 amino acid residues in the amino acid sequence of SEQ ID NO: 1, and imparting stability dependent on an oxygen concentration to other protein in a cell harboring a fused protein, when the polypeptide is fused with a nuclear localization signal and the other protein to form the fused protein.
